<Li> water (H 2O) </Li> <Li> ammonium hydrosulfide (NH 4SH) </Li> <P> Saturn is the sixth planet from the Sun and the second - largest in the Solar System, after Jupiter . It is a gas giant with an average radius about nine times that of Earth . It has only one - eighth the average density of Earth, but with its larger volume Saturn is over 95 times more massive . Saturn is named after the Roman god of agriculture; its astronomical symbol (♄) represents the god's sickle . </P> <P> Saturn's interior is probably composed of a core of iron--nickel and rock (silicon and oxygen compounds). This 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 has a pale yellow hue due to ammonia crystals in its upper atmosphere . Electrical current within the metallic hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is weaker than Earth's, but has a magnetic moment 580 times that of Earth due to Saturn's larger size . Saturn's magnetic field strength is around one - twentieth of Jupiter's . The outer atmosphere is generally bland and lacking in contrast, although long - lived features can appear . Wind speeds on Saturn can reach 1,800 km / h (1,100 mph), higher than on Jupiter, but not as high as those on Neptune . </P>
