Explore Saturn in 3D
Saturn is a gas giant best known for its broad ring system, made mainly of ice particles with smaller amounts of rocky material and dust.
- Main rings: about 270,000 km across
- Day: about 10.7 hours
- Average density: lower than water

About Saturn
Saturn is the sixth planet from the Sun and the second largest, a gas giant about nine times wider than Earth. It is famous for its rings, made mostly of water-ice pieces ranging from tiny grains to boulders several metres across. The main rings span roughly 270,000 km yet are often only tens of metres thick.
Saturn is the least dense planet — on average less dense than water. A day lasts about 10.7 hours and a year about 29.4 Earth years. Saturn has well over 100 known moons; the largest, Titan, is bigger than the planet Mercury and has a thick nitrogen atmosphere with lakes of liquid methane. NASA’s Cassini spacecraft studied Saturn from orbit from 2004 to 2017.
Saturn: frequently asked questions
What are Saturn’s rings made of?
Mostly chunks of water ice, from dust-sized grains to boulders several metres across, with small amounts of rock and dust.
Would Saturn float in water?
In principle, yes: its average density is lower than water’s. Of course, there is no ocean anywhere near big enough to try it.
How many moons does Saturn have?
Well over 100 confirmed moons, and the count keeps rising as new small moons are discovered. Titan is by far the largest.
