Saturn is the sixth planet away from the Sun in our solar system. Saturn is one of the four planets known as the "gas giants", along with Jupiter, Uranus, and Neptune. Like Jupiter, is made up of mostly the gas hydrogen. Saturn has giant rings made out of ice and rock that go around the planet. It also has lots of moons. One moon, which is called Titan has layers of gas around it, like the Earth. Some experts think that there may be alien life on Titan.
