Saturn is the sixth planet from the Sun in the Solar System. It is the second largest planet after Jupiter. Saturn was named after the Roman godSaturnus. Like Jupiter, Uranus and Neptune, it is a "gas giant". Saturn is best known for its rings which were first seen by Galileo Galilei in 1610 with his telescope. These rings which are only 10 m thick and 120,700 km wide, are made of ice, rocks and dust.
Saturn has 62 known moons, and the largest moon Titan, is larger than the planet Mercury. Saturn is about 1,400,000,000 km from the Sun. In the time it takes Saturn to complete one orbit of the Sun, or one Saturn year, the Earth has orbited 29.6 times, or 29.6 years on Earth.
