Facts About Saturn

Saturn is the sixth planet from the Sun and the second largest planet in our solar system.

Saturn is a massive ball made mostly of hydrogen and helium. It's surrounded by a beautiful ring system. It's the farthest planet from Earth discovered by the unaided human eye.

A view of Saturn from NASA Cassini spacecraft showing the planet's ring system.

NASA's Cassini spacecraft took this image of Saturn on Feb. 9, 2004, when the spacecraft was about 43 million miles (69 million kilometers) from the ringed planet. The image contrast and colors have been slightly enhanced to aid visibility.

Saturn and its glorious rings appear to glow in this image taken when the giant planet was backlit by the Sun.

With giant Saturn hanging in the blackness and sheltering Cassini from the Sun's blinding glare, the spacecraft viewed the rings as never before, revealing previously unknown faint rings and even glimpsing its home world.

Exploring Saturn

Four robotic spacecraft have visited Saturn.

NASA's Pioneer 11 provided the first close look in September 1979. NASA's twin Voyager 1 and Voyager 2 spacecraft followed up with flybys nine months apart in 1980 and 1981. Each flyby revealed intriguing details about the ringed giant world, but it wasn't until Cassini arrived in orbit in 2004 that our understanding of Saturn really started to take shape.

Moons of Saturn

Saturn has 146 officially recognized moons in its orbit, more than any other planet.

Saturn's moons range in size from Titan, which is larger than the planet Mercury – to a moon that's as small as a sports arena. Enceladus has a global ocean under a thick, icy shell.

More About Saturn's Moons

Against a black background, five golden-gray moons of varying sizes are scattered along a horizontal band through the image. Sunlight illuminates them from the left, and their right sides are in shadow. The largest, at far right, takes up the middle third of the photo, fully sunlit, with its dark half cut off by the right edge of the frame. The rings of Saturn, seen nearly edge-on, pierce the image like a knife blade from center-right, emerging through the largest moon, and with the smallest moon resting atop the blade like a breadcrumb.

On July 29, 2011, Cassini captured five of Saturn’s moons in a single frame with its narrow-angle camera.
