== Loop in astronomical categories ==

I noticed that [[:Category:Great Attractor]] is a subcategory of [[:Category:Norma Cluster]] which is a subcategory of [[:Category:Great Attractor]]. One of these relationships should be broken. The category system is supposed to be a hierarchy. So that if you keep selecting a subcategory, you eventually reach a category without subcategories. Another problem is that there seems to be confusion about which supercluster these belong to. Since I am not an astronomer, I brought these matters here rather than fix them myself.

=== Sorting Issues ===
It seems that the concern is actually over whether or not there is concensus for how to sort the pages that will be in [[:Category:Numbered asteroids]], so that multiple changes don't have to be made to so many articles. To help, I've gone through the numbered asteroids in [[:Category:Minor planets]] and [[:Category:Numbered asteroids]] and found:
{| class="wikitable" width="100%" style="text-align:center;"
!style="background:#CCCCCC;" width="60%" | Numbered Asteroids in Category:
!style="background:#CCCCCC;" width="20%" | [[:Category:Minor planets]]
!style="background:#CCCCCC;" width="20%" | [[:Category:Numbered asteroids]]
|-
|Pages that use <code><nowiki>{{DefaultSort:<alphanumeric>}}</nowiki></code>
|16,429 (85.4%)
|539 (95.6%)
|-
|Pages that use <code><nowiki>{{DefaultSort:<numbers only, w or w/o "()">}}</nowiki></code>
|1,477 (7.7%)
|25 (4.4%)
|-
|Pages without "<code><nowiki>{{DefaultSort</nowiki></code>"
|1,331 (6.9%)
|0
|-
|Total
|19,237
|564
|}

There are other categories such as [[:Category:Asteroids named for people]] for the named asteroids, which is probably why there are 12,335 using <code><nowiki>{{DefaultSort:<name>}}</nowiki></code>. Therefore, most straight-forward solution I see is to (with a bot request or 2):
# Explicitly use <code><nowiki>[[Category:Numbered asteroids|<a 0-padded 6-digit number>]]</nowiki></code> on all current and future additions to this category. 11 of the 564 pages currently use this sortkey.
# Explicitly use <code><nowiki>[[Category:Asteroids named for people|<the non-numeric portion of the asteroid's name>]]</nowiki></code> on all current and future additions to these types of categories which rely on name.
# Not sure how best to handle the {{tl|DefaultSort}} discrepancy. I'd say leave it alone for now, and deal with it after we've sorted out the category sorting<sup>pun!</sup> (but I naturally prefer using a 0-padded 6-digit number, and since the most important (lowest numbered) asteroids are already {{tl|DefaultSort}}ed this way).
What're everyone's thoughts on this? &nbsp;&nbsp;<b>~</b>&nbsp;<span style="font-family:Monotype Corsiva; font-size:17px;">[[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]] ⋅[[Special:Contributions/Tom.Reding|contribs]] ⋅[[WP:Don%27t-give-a-fuckism|dgaf]])</span>&nbsp; 18:54, 27 May 2015 (UTC)
:First of all, it appears your number of objects with numbers instead of names is perhaps(?) incorrectly counted, as nobody had used the 0-padding 6-digit number sort before me, and I find it hard to believe 10 times more asteroids than I had edited are already using this. However, the current sort is to list the name of an asteroid, and if it does not have a name to simply include the provisional designation. As a result, I believe your defaultsort:<number> asteroid listings are off by approximately an order of magnitude. [[User:Exoplanetaryscience|exoplanetaryscience]] ([[User talk:Exoplanetaryscience|talk]]) 19:36, 27 May 2015 (UTC)
::Hmm, in my search I looked for either a number or an A-Z character (case insensitive) after "{{DefaultSort:" (also case-insensitive) with the possibility of spaces after the colon and/or an opening parenthesis, so you're right, I think I certainly picked up a lot of numbered asteroids which are sorted by their provisional designation. I'll run this search again, except looking for number-only sortkeys. I updated the table above to reflect this and I'll update it again once I'm finished. &nbsp;&nbsp;<b>~</b>&nbsp;<span style="font-family:Monotype Corsiva; font-size:17px;">[[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]] ⋅[[Special:Contributions/Tom.Reding|contribs]] ⋅[[WP:Don%27t-give-a-fuckism|dgaf]])</span>&nbsp; 20:03, 27 May 2015 (UTC)

:::A remark concerning the 0-padding. Right now, because there are asteroids under 10000, you only need to pad with 3-zeroes at most (e.g. 0001-9999). If you include asteroids with numbers under 100000, you would need pad with 4-zeroes  (e.g. 00001-99999). The exact number of zeroes things should be padded with depends on the biggest asteroid number. If the largest asteroid numbers is say ~975000, then it's likely that the million threshold will be crossed soon, so we should plan ahead and sort things to accomodate asteroid number 0000001 to 9999999. If it's 25000, then padding to accomodate asteroid number 000001-99999 is reasonable. I mentionned 6 zeroes because I can't recall seeing something with a number above a million, but that many zeros may not be needed, or more might be required.
:::Now concerning what should be done, IMO, explicit sorting by number in :[[:Category:Numbered asteroids]] and by name in [[:Category:Asteroids named for people]] seems the best. For the defaultsort, let's imagine what should happen when they are in something fairly generic, like [[:Category:Radar-imaged asteroids]]. IMO, things should be sorted according to asteroid number. So to me, it seems like a good argument for defaultsorting according to number, except perhaps in the case of Ceres, Vesta, and similar.

::::Also, I'd previously been sorting asteroids by articles simply containing physical or orbital characteristics by their numeric designation, or provisional if not available; Asteroids in categories pertaining to their name e.g asteroids named from greek mythology are sorted using their names; Asteroids in categories relating to dates are sorted by significant dates- Asteroids visited by spacecraft I sorted by the date visited, Astronomical objects discovered in YYYY I sort by the date discovered, Near earth objects in YYYY I sort by closest approach, and comets in YYYY I sort by the perihelion date if in that year, a close approach made by that comet in the year, or the comet's discovery date, in that order of preference.
::::Based on this, I sort asteroids with numeric designations as a six-digit number. For [[4 Vesta]], for instance, I would sort 000004; and for [[385446 Manwë]] I would sort 385446.

Additionally the time of the discovery in decimal in UTC can be included, but isn't necessary again for the purpose of simplicity.
::::Comets with numbers are expressed as PNNN, with N being the number. For instance, [[Halley's Comet]] is P001. The presence of the P is to separate Periodic comets from numbered asteroids in categories of both.
::::Comets with provisional or normal designations are assigned based on their orbit type, year, and designation. [[C/1980 E1]] would be represented C1980E01. [[D/1770 L1]] would be represented D1770L01. [[P/1997 B1]] would be represented P1997B901. [[X/1106 C1]] would be represented X1106C01

::::As of last week, [[(432949) 2012 HH2]] is the highest-numbered asteroid in [[:Category:Minor planets]]. According to the [http://mpc.cfa.harvard.edu//mpc/summary MPC], there are currently 433,937 numbered, 247,275 unnumbered, and 685,070 total minor planets. That works out to the IAU numbering ~330 asteroids/year. And judging by the fact that there are [[WT:AST#Summary of Remaining Redirected & Unredirected Asteroid Articles|roughly the same #]] of unredirected asteroids from 2000-433,000 as there are from 1-2000 (i.e. lack of notability strongly correlates with number), 6 digits is probably good for a while. &nbsp;&nbsp;<b>~</b>&nbsp;<span style="font-family:Monotype Corsiva; font-size:17px;">[[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]] ⋅[[Special:Contributions/Tom.Reding|contribs]] ⋅[[WP:Don%27t-give-a-fuckism|dgaf]])</span>&nbsp; 21:48, 27 May 2015 (UTC)

== Creation of additional categories for multiple-designation objects ==

Certainly anyone who has done searches into asteroids' provisional designations for wikipedia or otherwise has noticed that a large portion (if not all of) of the first discovered asteroids have multiple designations from before there were easy ways to discover if the object you're observing is already known or not. Even some of the first asteroids have multiple designations. Ceres is additionally known as A899 OF and 1943 XB. Astraea is known as 1969 SE. However only one date is included in the Category:Astronomical objects discovered in [year], so I propose that asteroids discovered multiple times, and given multiple designations, be either sorted into a separate category, for instance Category:Asteroids rediscovered in [year], or something similar. Or, alternatively, be sorted into multiple discovery year categories. Additionally, while I'm on the topic, a number of asteroids discovered after around #300 are listed as being discovered multiple times, but a true date of discovery is included because after observations on the previous dates, it was lost. Should its discovery date noted on the article be the most recent one of which sufficient observational data was found to have it not be considered a lost asteroid, the first discovery date displayed, or should both discovery dates be listed? [[User:Exoplanetaryscience|exoplanetaryscience]] ([[User talk:Exoplanetaryscience|talk]]) 21:04, 28 May 2015 (UTC)

:Regarding the first part, would <nowiki>[[Category:Asteroids with multiple designations]]</nowiki> be sufficient? Then, an interested reader can look up the various designations, which should be in the infobox. The alternative seems a bit clunky. &nbsp;&nbsp;<b>~</b>&nbsp;<span style="font-family:Monotype Corsiva; font-size:17px;">[[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]] ⋅[[Special:Contributions/Tom.Reding|contribs]] ⋅[[WP:Don%27t-give-a-fuckism|dgaf]])</span>&nbsp; 21:45, 28 May 2015 (UTC)

::Well my reason for suggesting as described is that when an asteroid has multiple 'discovery' dates, should the first discovery date simply be included, even if it was subsequently lost and rediscovered several decades later?

:All numbered asteroids have multiple designations. They have their provisional designation, their number, and if they have names, their name. So many have atleast 3 designations.

== On a revision of the categorization of astronomical objects ==

There are quite a few important categories relating to astronomy on wikipedia, and groups of categories. These range from category groups like Category:Astronomical objects discovered in [year], Category:Discoveries by [astronomer], and Category:[spectral type]-type asteroids, to more specific categories like Category:Quasars, Category:Multiple star systems, or Category:Kuiper belt objects. Every one of these categories contains a fairly large amount of objects in it and covers an important topic, but in most of these cases, and in quite a few more, there is no clearly established system or sort order for these objects, and in this discussion I seek to put an end to this, and provide a consensus for the outcome of this.

PROPOSALS:
***keep in mind wikipedia's entire database, for better or for worse, is driven and only held up through consensus and majority, so none of these suggestions are rules unless the majority of WP:AST should deem it so.

*For minor planets and solar system objects:
:*For asteroids:
:#For default:<br>1a. For '''numbered''' default: sorted by a 0-padded 6-digit Minor Planet Center number (642 Clara would be sorted 000642, 19731 Tochigi would be sorted 019731, and (52430) 1994 PF8 would be sorted 052430).<br>1b. For '''provisional''' default: If it does not have a numbered designation, the provisional designation would be sorted YYYY MNNNL, in which 2015 FG345 would be sorted 2015 F345G, 1992 QB1 would be sorted 1992 Q001B, and 2014 RC would be sorted 2014 R000C. This is to establish hierarchy of the classification, as 2014 RC was discovered before 2014 RA1, yet would be sorted after. In this situation, they would be sorted 2014 R000C and 2014 R001A, sorting it appropriately
:#For name sorts: The asteroid's name would be included in categories directly relating to the name of the asteroid, such as Category:Asteroids named for people, or Category:Asteroids named for places.
:#For date sorts: Specifically for Category:Astronomical objects discovered in (year), asteroids, comets, and all other objects will be sorted by YYYYMMDD of discovery in UTC- the introduction of the year, even though it is implied, is because without the year included it would simply be MMDD, and would end up in a separation of some objects sorted with a 0 and some with a 1- objects discovered in January to September, and October to December.
:*For comets:
:#For default: Numbered comets will be sorted as (A)NNNN- where the N is the designation of the comet. A is invariable and simply serves as a discriminant as to not confuse comets and asteroids, as well as establish numbered comets before unnumbered comets. comet 1P/Halley would be sorted A0001, and comet 34D/Gale would be sorted A0034.
:#Unnumbered comets are sorted as PYYYYMNN with P being the orbit of the comet- X, D, P, or C, and YYYYMNN being the comet designation, formatted much the same way as asteroids- Caeser's comet would be C-043K01, C/2013 US10 would be C2013U010S, P/2012 F5 would be P2012F05, and D/1993 F2-K would be D1993F02K.
*For other astronomical objects
#For multiple stars (more than 3): The exact number of stars in the star system, it's quite simple
#default: sorted by distance, padded designation if categorized by a non-RADEC catalog, or discovery date?
I would recommend the exact sort format be provided on each category's page, as the sort format could quickly become quickly confusing and conflicting.

These are my proposals, yea or nay? Also, any comments or input? This is still a work in progress, and most of this I have based only on what I have encountered so far on wikipedia. Either way, I believe that this could be immensely helpful for providing meaningful information on Wikipedia, and I hope others will see this too.

:I cannot comment on all of the proposals here, but I say "For other astronomical objects" just go with the status quo, categories listed in distances would surely rupture categories listing objects by entries of their catalog (ex. {{cat|Exoplanets discovered by Kepler (spacecraft)}}, {{cat|Exoplanets in the Gliese Catalog}}, etc.). <span style="border:2px solid #090E0E;padding:0px;"><font style="color:#FFFFFF;background:#000000;">[[User:Davidbuddy9|Davidbuddy9]]</font>[[User talk:Davidbuddy9|<font style="color:#000000;background:#FFFFFF;">&nbsp;Talk&nbsp;</font>]] </span>

::: Thx for addressing these issues.

:: In addition, most of the <code><nowiki>[[Category:Discoveries by <astronomer-name>]]</nowiki></code> in minor planets articles do not make much sense to me. Why not directly list the bodies in the article about the astronomer? This would also simplify the inconsistent sorting-issue of categories, as mentioned above. For example the article about the astronomer [[Nikolai Chernykh]] already lists his discoveries, while the redundant [[:Category:Discoveries by Nikolai Chernykh]] is incomplete (probably 50% of the bodies are missing). While it's easy to create a new category, it is much harder to make sure all articles are added in the correct sorting order.

It is my opinion that readers are most likely to search for an article by its title. In the case of minor planets, this means the name, or if there is none, the number. In the case of stars, nebulae, galaxies, etc., this would mean the most commonly used designation, or common name if that is used more. I think that the categories should be arranged so that it is easy for readers to find articles they want, so they should be ordered by name/designation.

I think a reasonable course of action is, as expolanetaryscience suggested, to state on each category page exactly how it should be sorted, both for preliminarily-designated objects and for numbered objects, but only if the intended sorting method for each category is obvious. If the category is a mess, we should discuss them individually, preferably on their talk page, but placing a link here ([[WT:AST]]) so that all may participate. &nbsp;&nbsp;<b>~</b>&nbsp;<font style="font-family:Monotype Corsiva; font-size:16px;">[[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]] ⋅[[WP:Don%27t-give-a-fuckism|dgaf]])</font>&nbsp; 16:05, 9 January 2016 (UTC)

For the asteroids#1b (and comets#2) proposal for '''preliminary designations''' only (i.e. [[1991 BA]], not [[(3708) 1974 FV1]]), why are we trying to keep preliminary designations ordered by date of discovery in a non-chronological category? Isn't that the job of [[:Category:Astronomical objects by year of discovery]]? Turning "1992 QB1" into "1992 Q001B" seems unnecessarily confusing and could easily be done incorrectly. Any category explicitly or implicity sorted by name ([[:Category:Minor planets]], for example, implies sorting by the object's name), the name of the article should be used (with the ''rare'' exception, which these names are not; they are the norm in their number range). This doesn't relate to numbered asteroids, whose sorting proposal I agree with. And even numbered asteroids are not sorted chronologically (they're only "roughly" chronological). &nbsp;&nbsp;<b>~</b>&nbsp;<font style="font-family:Monotype Corsiva; font-size:16px;">[[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]] ⋅[[WP:Don%27t-give-a-fuckism|dgaf]])</font>&nbsp; 16:30, 17 January 2016 (UTC)

== [[:Category:Numbered asteroids]] Maintenance ==

It's been a few months since [[User:exoplanetaryscience|exoplanetaryscience]] brought up the [[User talk:Tom.Reding#Asteroid list|point]] that most of the [[User:Exoplanetaryscience/List of numbered asteroids|~19,200 numbered asteroids]] are not contained in [[:Category:Numbered asteroids]] (current population = 1,605). [[Wikipedia:Bot requests/Archive 64#Request for category adding|This bot request]] was made shortly after, but never performed. The archived WT:AST discussion we had alongside the botreq is [[Wikipedia talk:WikiProject Astronomy/Archive 18#Bot Request for Category:Numbered asteroids Maintenance|here]] (I'm only concerned with point #1 at the moment); the consensus of which was to add a 0-padded 7-digit sort key to the end (<code><nowiki>[[Category:Numbered asteroids|0000001]]</nowiki></code>) while adding the category to all of the ~19k pages. I'm thinking about taking up this request in the near future (as I did with the then-incomplete request to selectively redirect the many asteroid stubs), so I'll ping all those previously involved to see if any opinions have changed or been added, since I haven't really kept up with WP:AST, nor WP in general, over the last 6 months.

:::::::I agree on adding the category to all non-redirects. I've been doing so myself for the last few months to all edits tagged "overall revision". I wouldn't use that category on redirect (though I might have done so on a few occasions), as there is already a complete list, [[List of minor planets: 1–1000]]. I have been removing all self-redirect on that list up to #200,000 and now is easy to see how the actual articles get thinner and thinner. So a "compact" (not really) category, listing only articles, is much better. Also, I normally added the "Category:Numbered asteroids" in 2nd position, after the Main-belt/family category and before the "Discoverer" category. If everybody adds a 6-digit sortkey to that category, I will do so as well. (Until recently only up to #2,000 the category entries were numerically sorted, from there on, in 99% of all cases, the higher numbered bodies were sorted by the standard name-based on the DEFAULTSORT key). <em>[[User:Rfassbind|<span style="font-weight:bold;color:forestgreen;"><span style="color:#a2a2a2;">R</span>fassbind</span>]] <small>[[User talk:Rfassbind|&ndash; talk]]</small></em>  15:17, 7 January 2016 (UTC)
::::::::Indeed, I have been placing that category in the 2nd position, though not intentionally. I first attempt to place the category (if non-existent) alphabetically against other categories that begins with 'N', going from the top down. If unsuccessful, alphabetically against 'M' categories (Main-belt asteroids, usually). If unsuccessful, alphabetically against 'L-A' categories. If still unsuccessful, alphabetically before O-Z cats. If ''still'' unsuccessful, then I just put it at the end.

::::::::For minor planet article names of the form '''(#####) YYYY Wwwww''' (where w's are word characters), I added a 6-digit sortkey at the end of [[:Category:Numbered asteroids]] no matter what the DEFAULTSORT. I decided on this after seeing at least 3 (if not 4) different DEFAULTSORT variations for this group: 0-padded 6-digit, "YYYY Wwww", and "(#####) YYYY Wwwww" ("##### YYYY Wwwww" probably exists too, but I wasn't interested in getting that specific), with no clear pattern. The first 2 variants are roughly equally common, and the 3rd is less common. The categories did not seem to always account for these DEFAULTSORT variants. More category maintenance is needed here, and I don't trust the average editor to keep Cat:Numbered asteroids tidy (nor the other cats, but I'm only focusing on Cat:NA at the moment; see the semi-proposal below).

::::::::For minor planet article names of the form '''##### Wwwww''', especially those numbered 1-2000, I'm only adding a 6-digit sortkey if the DEFAULTSORT is not already 6-digits. This might change as I go up in number, if I see a lot of disorder. As of ~1/2 way through, I'm deciding to add a 6-digit sortkey IF other categories on the page also have one, regardless of the DEFAULTSORT. I'll be making a 2nd pass through all the minor planets to include this and other rule changes I've made since I started.

::::::::For minor planet article names of the form '''##### WW''' (where W's are upper case word characters), I'm not adding the category since these are still provisionally designated.

::::::::Finally, I'm also checking for non-numeric [[:Category:Numbered asteroids]] sortkeys and replacing them with 6-digit ones. There have been 1-to-a-few dozen of these so far, and I'm 1/3 of the way through.

::::::::'''Semi-proposal:''' Ideally, ''every'' category has a consistent sorting method for all its children. A variable DEFAULTSORT only adds a layer of complexity to the semi-automated check. Going through ''manually'' would be a source of error (at least for me). There're '''2''' ways to approach this: 1) enforce a standard DEFAULTSORT on all articles, then adjust each cat's sortkey for consistency, or 2) abide by the current DEFAULTSORT, then adjust each cat's sortkey for consistency. Since each cat needs to be checked anyway, I'm slightly in favor of #2. Either way, a sort order for each category needs to be established (which is probably obvious, and the prevailing and most intuitive order by just looking at the cat, but I haven't looked at all the various minor planet cats).

::::::::''If I were given'' an explicit list of cats and their preferred sort order (consensus approved, if currently ambiguous), I would do this.

:::::::::It's my strong conviction that the magic word DEFAULTSORT is detrimental, as it is a source for well-meant bad ideas. Soon someone will come up with a 7 or 8-digit Sortkey and change a few hundreds articles/redirs before anyone will notice the changes.

::: The 201 categorized redirects were done intentionally, so there's no need to change anything. I'd rather fix an existing category on a redirect than to remove the cat. Otherwise, this would send a mixed message to future editors, or the cat might be lost if/when the redirect is reverted, if the cat was added to the redirect. Keeping [[:Category:Numbered asteroids]] clean of redirects is not a particularly worthwhile task, especially for those articles bouncing in and out of redirect; it's best just to keep the category on the page.

== [[:Category:Astronomical objects by year of discovery]] mass-sterilization ==

While working for a while on the minor planet redirects, and with [[WT:AST#On a revision of the categorization of astronomical objects|considerable]] [[User talk:Tom.Reding/Shortlist of minor planet redirect candidates#(minor) proposed edit changes to filters and templates|prodding]] from {{U|exoplanetaryscience}}, I finally made an AWB rule-set which grabs discovery year, month, and day from the article text or from the infobox parameter {{para|discovered}} (in that order, and, if both exist, checks for agreement ([https://en.wikipedia.org/w/index.php?title=170906_Coluche&diff=prev&oldid=699644620 text wrong], [https://en.wikipedia.org/w/index.php?title=9937_Triceratops&type=revision&diff=699724838&oldid=699482570 text & infobox wrong])) and adds the corresponding YYYYMMDD sortkey, which is the sole sortkey-format I've seen for these categories. I want to run this on all pages contained in the 255 subcategories of [[:Category:Astronomical objects by year of discovery]] in the near future, so I figured I'd warn everyone. There will invariably be another shortlist of exceptions, but it'll be a lot easier to go through that once the easy-to-fix cases are taken care of.

Also, I'm tempted to put a note on this parent-category, and the 255 subcategories, explicitly stating the sortkey format<s>, before I start</s>.

== [[:Category:Minor planets]] Sterilization ==

I'm going to tackle this very soon, at least in part.

For the '''numbered minor planets only''', I will check for, and soft-handedly enforce the logic: {{nowrap|(DEFAULTSORT {{!}}{{!}} Category sortkey) {{=}}{{=}} 0-padded 6-digit (0p6d)}}, in the following ways:
# If "<code><nowiki>{{DEFAULTSORT:</nowiki></code>" is absent from the text, I will add <code><nowiki>{{DEFAULTSORT:<0p6d>}}</nowiki></code>, for 3 reasons:<br>1a. There are more asteroid categories which sort by ''number'' than there are that sort by ''name''.<br>1b. All asteroid categories which sort by name, that I'm aware of, have been sterilized by me, and already use the proper DEFAULSORT/sortkey combination.<br>1c. Most of the objects discovered by multiple people, and hence with multiple <nowiki>[[Category:...discovered by <blah>]]</nowiki>s already use the more-appropriate ''alphabetic'' DEFAULTSORT.
# If a 0p6d DEFAULSORT and 0p6d cat sortkey exist, I won't touch anything ([[WP:GENFIXES]] removes the cat sortkey in this case).
# If a 0p6d DEFAULSORT and '''!'''0p6d cat sortkey exist, I'll remove the cat sortkey.
# If a '''!'''0p6d DEFAULTSORT and '''!'''0p6d cat sortkey exist, I'll correct the cat sortkey to 0p6d.
# If a '''!'''0p6d DEFAULTSORT and 0p6d cat sortkey exist, I won't fix anything, since [[Wikipedia:IFITAINTBROKE|it ain't broke]].<br>5a. If the DEFAULTSORT != (0p6d || <name> || <prelim>) then it is removed. Goto rule #1.
# If, after my changes, ''all'' cats on the page have a 0p6d sortkey, then the existing DEFAULTSORT is effectively useless. Replace the useless DEFAULTSORT with the 0p6d one, and remove the sortkey from all cats.

That should account for all permutations.

I'll take care of the '''preliminary designation''' asteroids later, maybe, [[#On a revision of the categorization of astronomical objects|after we come to a firm consensus]]. &nbsp;&nbsp;<b>~</b>&nbsp;<font style="font-family:Monotype Corsiva; font-size:16px;">[[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]] ⋅[[WP:Don%27t-give-a-fuckism|dgaf]])</font>&nbsp; 20:23, 17 January 2016 (UTC)

===Preferred sort for [[:Category:Discoveries by astronomer]]===
This is a fairly large uncle-category which appears on most minor planet pages: 177 subcats, 7,637 unique pages, 9,522 non-unique pages, only 1 cat deep. Either someone has gone through a lot of trouble to sort ~66% by prelim, or no one decided to (or had the energy/desire/ability to) challenge the <code><nowiki>{{DEFAULTSORT:YYYY WW#}}</nowiki></code> convention, until now. Either way, here's a summary of the 8 most-populated subcats, representing 42.5% of all categorized pages, and how they're sorted.

What I'm about to do is pretty much a 1-way street right now, at least if/until AWB implements a <code>$pagetitle$</code> feature, or the like, which I've recently [https://phabricator.wikimedia.org/T123925?workflow=create requested here] (but I'm half convinced I'm simply throwing my request into a [[black hole]], since I have ~12 still-open requests from a year ago). Grabbing the ''numeric'' or ''name'' portion of MPs is easy, but as soon as we're allowed to use {{tlx|mp}} for the page, it gets really, really hard to make a reliable regex pattern to always get the page name and nothing but the page name, which would need to be operated on several times to get back to how it is. That's why I want to be very careful, and certain, about doing this.
:::This is resolved, since <code>%%pagename%%</code>, thankfully, exists! It was just not easily found in the AWB documentation. 2-way street established; hesitation diminished. &nbsp;&nbsp;<b>~</b>&nbsp;<font style="font-family:Monotype Corsiva; font-size:16px;">[[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]] ⋅[[WP:Don%27t-give-a-fuckism|dgaf]])</font>&nbsp; 16:49, 19 January 2016 (UTC)

: '''Oppose''' I've been editing the sortkey of the [[:Category:Discoveries by astronomer]]-subcategories for vast number of articles and redirects. The order of listing was a complete mess (for several reasons, such as change of DEFAULTSORT key, lousy implementations of redirects, or neglected update of recently named bodies). Now, you propose to sort them by number and no longer by name. Oh well... Fact is that many/most articles about astronomers, who discovered minor planets, contain a wikitable with their discoveries. As these wikitable are all sorted by number, sorting the category also by number would be redundant. Sorting the categories by name would avoid that redundancy. In addition, sorting by name creates more subsection (A-Z), not just one or two subsection (0 and 1). Also, sorting by name separates named minor planets from those with a provisional designation. (Former may have an article, latter is most likely a redirect). For all these reasons, sorting by name is better, but most importantly a consistent sort order is needed. For example, here are some "discoveries-by" subcats I revised to consistent a sorting by name. Previously they were a complete mess.

:: I'm literally just fishing for arguments, and these are all good.

:: The goal of the table above was to test whether the cat's composition (i.e. 95% #+prelim) had an equal sort-% of ''some'' kind (i.e. either 95% by #, or 95% by prelim). Because some of them had very different composition-% vs. sort-%, I became very hesitant. Given your reasoning, and the fact that the majority sort for these cats is by name, the question now is: why ''shouldn't'' I sort these name? That's a hard question to answer now, but we'll see.

I'm thinking about putting the non-family-member, prelim-only pages in a child [[:Category:Main-belt preliminary asteroids]], since there are comparatively so few pages of them.

All numbered asteroids (named & unnamed) should now be sorted properly. ~17,600 edits made, 72 categories created, and 24 "(<number>) <name>" asteroids had their categories stripped to avoid duplication. All new categories, and most existing ones, have a [[WP:SORTKEY|sortkey]] note at the top either explicitly stating their sort convention for asteroids, or a note pointing to their parent, which has the explicit convention, lest they drift in the future.

Very minor exceptions are 1) between 50-75 [[:Category:Numbered asteroids]] are on #REDIRECT pages (1.8% of that category), and 2) 110 and 316 [[:Category:Astronomical objects by year of discovery]] with either a "?" or empty sortkey, respectively. &nbsp;&nbsp;<b>~</b>&nbsp;<span style="font-family:Monotype Corsiva; font-size:16px;">[[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]] ⋅[[WP:DGAF|dgaf]])</span>&nbsp; 05:35, 29 January 2016 (UTC)

::<small>(Copied from the cat talk page)</small> Right now, (almost) all "worthwhile" MP #Rs (excluding #Rs for typos, renames, misspellings, etc.) are in the [[:Category:Minor planets]] hierarchy, but alongside legitimate articles.

== Preferred sort for [[:Category:Discoveries by PLS]] ==

To let [[:Category:Palomar–Leiden survey]] conform to the [[:Category:Discoveries by institution]] hierarchy, its contents are being moved (and expanded) into [[:Category:Discoveries by PLS]]. The [[WP:SORTKEY|sortkey]] for [[:Category:Palomar–Leiden survey]] is its preliminary P-L designation, which is removed from the article's title when given a name, and (hopefully) added to/kept in the article text (standard for all MPs, as far as I can tell). The sortkey for ''all other'' [[:Category:Discoveries by institution]] child categories is 0-padded 6-digit (maybe because their survey designations are either hard to find, or complicated).

My question is, do we want to:
# Keep the P-L designation sortkey, and, by extension, all other survey-designation sorkeys, or
# Replace the P-L designation sortkey with a 0-padded 6-digit (this would affect 99.8% of [[:Category:Palomar–Leiden survey]] (all but 1))

Seems like it would be easier to visually identify that way. <span style="white-space:nowrap; text-shadow:gray 5px 3px 1px;">— [[User:Huntster|Huntster]] <small>([[User talk:Huntster|t]] [[Special:Emailuser/Huntster|@]] [[Special:Contributions/Huntster|c]])</small></span> 03:22, 10 February 2016 (UTC)

::We could. I've held off on editing anything P-L related until/if there's a firm direction here. I/we try to balance complexity, readability, and addability when naming categories. [[:Category:Discoveries by the Palomar–Leiden survey]] is in the middle, somewhere between [[:Category:Discoveries by the Palomar Observatory]] and [[:Category:Discoveries by OLS‎]], so it can go either way. The ndash is the main issue, since, to add the category properly, it takes the extra steps of looking up which dash-symbol it uses (n, m, or keyboard, minus?), which is a source of error if an editor isn't careful. I would only feel comfortable with a small constellation of category #redirects to [[:Category:Discoveries by the Palomar–Leiden survey]] to alleviate the possibility of this. If there are bots that move cats from cat-#Rs to their target, great; if not, I prefer [[:Category:Discoveries by PLS]]. &nbsp;&nbsp;<b>~</b>&nbsp;<span style="font-family:Monotype Corsiva; font-size:16px;">[[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]] ⋅[[WP:DGAF|dgaf]])</span>&nbsp; 13:49, 10 February 2016 (UTC)

:::{{u|Tom.Reding}}: Moving items to a new category is easy-peasy with AutoWikiBrowser, so just let me know exactly what you want the name to be, and I'll take care of the moves. I can also move everything out of [[:Category:Palomar–Leiden survey]] to whatever the target is, easily, if I'm correctly understanding that this is the end goal. As to your original question, if the designation numbers are now static (aka no more are being created, and I assume this is the case since the survey took place in the 1970s), then I see no reason to switch to the 6-digit key...that's only useful if you're trying to future-proof an ever-expanding data set. <span style="white-space:nowrap; text-shadow:gray 5px 3px 1px;">— [[User:Huntster|Huntster]] <small>([[User talk:Huntster|t]] [[Special:Emailuser/Huntster|@]] [[Special:Contributions/Huntster|c]])</small></span> 17:01, 10 February 2016 (UTC)

::::My concern isn't the initial moves (I've got 1300 lines of code & ~150 custom AWB rules fixing & sorting MP pages). My concern is unnecessary (or easily avoided) category maintenance in the future, since we have yet to categorize all of the P-L objects. Do you know if a bot takes care of cat-#R moves (moving a page from a cat-#R to the target)? I see [[:Category:Main Belt asteroids]] and the like moved to [[:Category:Main-belt asteroids]], <s>but there are no cat-#Rs to the proper name</s>, so this is very likely done due to popular demand, and not universally. I wanted to save some time here, but I'll ask the bot owner too ([[User talk:R'n'B#Automatic category-redirect moves|discussion here]]).

{{od|5}}With help from {{U|Rfassbind}}, all objects currently associated with the Palomar–Leiden survey cats and the Trojan surveys cats are now sorted into their discovery and/or survey catalog cats. The hierarchy can be seen starting at [[:Category:Asteroid surveys]],  [[:Category:Astronomical surveys]], and [[:Category:Palomar Observatory]]. I'll continue to search for PL objects as I progress through the MPs, and on pages I've already gone though. &nbsp;&nbsp;<b>~</b>&nbsp;<span style="font-family:Monotype Corsiva; font-size:16px;">[[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]] ⋅[[WP:DGAF|dgaf]])</span>&nbsp; 19:44, 17 February 2016 (UTC)

*'''Suggestion''' [[:Category:Stars with proper names]] tends to be stars visible with the naked eye from Earth (or at least stars from constellations that have some stars visible from Earth).  For Wikipedia readers who are--let's face it--mostly on Earth, that might aid navigation. I'm not clear on how named centaurs are physically different than the ones with numbers assigned to them. You don't need my permission to create categories of course, but it might be worth seeing how the discussions (above and below) turn out if creating these would be time consuming.

:*{{U|RevelationDirect}}, at least we can agree that 'Named minor planets' is a significant category. To make that category more tractable, since it will contain ~20,000 entries, it would be useful to subdivide it into its major components. What determines a "major" component, however, I'll leave up to others. &nbsp;&nbsp;<b>~</b>&nbsp;<span style="font-family:Monotype Corsiva; font-size:16px;">[[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]] ⋅[[WP:DGAF|dgaf]])</span>&nbsp; 20:39, 14 August 2016 (UTC)

::*On further inspection and on second thought, since [[:Category:Numbered minor planets]] & [[:Category:Unnumbered minor planets]] (the categories which [[:Category:Named minor planets]] is meant to compliment) aren't themselves further subdivided, I'm much less inclined to do so. Doing so would require more input and interest than is present here, since it would be departing from convention. Doing so would also result in duplicate category trees, be susceptible to drift, and require an additional level of maintenance. &nbsp;&nbsp;<b>~</b>&nbsp;<span style="font-family:Monotype Corsiva; font-size:16px;">[[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]] ⋅[[WP:DGAF|dgaf]])</span>&nbsp; 19:54, 17 August 2016 (UTC)
