Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine times that of Earth . It only had one eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive . Saturn is named after the Roman God of wealth and agriculture; it's astronomical symbol represents the God's sickle . The outer atmosphere is generally bland and lacking in contrast although long lived features can appears.
Saturn interior is most likely composed of a core of iron nickel and rock ( silicon and oxygen compounds ). It's core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally a gaseous outer layer . Saturn had pale yellow due to ammonia crystals in its upper atmosphere. Wind speeds on Saturn can reach 1800 km/h .
The planet's most famous feature is its prominent ring system, which is composed mostly of ice particles, with a smaller amount of rocky debris and dust . At least 82 moons are known to orbit Saturn . Saturn is a gas giant because it is predominantly composed of hydrogen and helium. It lacks a definite surface, though it may have a solid core. Saturn rotation causes it to have the shape of an oblate spheroid; that is it is flattened at the poles and bulges at its equator.
