Tycho Brahe
Tycho Brahe was a Danish astronomer who lived between 1546-1601. For
over twenty years, he made very accurate observations of the night sky, all
without the aid of a telescope, which had not yet been invented. Tycho also built the world's first observatory and kept a star catalogue with over 1000 stars.
Tycho's records were used by Johan Kepler to describe the orbits of planets around the sun and disprove the Ptolemaic theory.
