 My inquiry question is: = __**What are the physical characteristics of Saturn?**__  = Saturn is the second largest planet in our solar system, the biggest being Jupiter. The average distance between Saturn and the Sun i s over 1,400,000,000 km (9 AU). It takes Saturn 10,759 Earth days (or about 29½ years), to finish one revolution around the Sun.

Saturn's radius is nine times that of Earth, and it is 95 times bigger than Earth, but its density is only 1/8 that of Earth's. Saturn's core is the only solid surface. Saturn's core is probably made up of rock, iron, and nickel. The core is surrounded by a deep metallic hydrogen and liquid helium layer, which is then surrounded by an outer gaseous layer. The gaseous layer is made up of 96.3% molecular hydrogen and 3.25% helium. That is surrounded by the atmosphere. Saturn's atmosphere is made up of 75% hydrogen, 25% helium. Little amounts of ammonia, acetylene, ethane, propane, phosphine and methane have been detected in Saturn's atmosphere. Saturn is famous for its rings. They are made up of 93% water ice with traces of tholin impurities and 7% amorphous carbon. The rings extend from 6,630 km to 120,700 km above Saturn's equator, average approximately 20 meters in thickness. The particles that make up the rings range in size from specks of dust up to 10 meters. Saturn has 62 moons, 53 of them are named. Saturn's moons are: Aegaeon, Aegir, Albiorix, Anthe, Atlas, Bebhionn, Bergelmir, Bestla, Calypso, Daphnis, Dione, Enceladus, Epimetheus, Erriapus, Farbauti, Fenrir, Fornjot, Greip, Hati, Helene, Hyperion, Hyrokkin, a petus, Ijiraq, Jarnsaxa, Janus, Kari, Kiviuq, Loge, Methone, Mimas, Mundilfari, Narvi, Paaliaq, Pallene, Pan, Pandora, Phoebe, Polydeuces, Prometheus, Rhea, Suttungr, Skathi, Siarnaq, Skoll, Surtur, Tarqeq, Tarvos, Telesto, Tethys, Thrymr, Titan, and Ymir. Saturn's Provisional moons are: S/2004 S 7, S/2004 S 12, S/2004 S 13, S/2004 S 17, S/2006 S 1, S/2006 S 3, S/2007 S 2, S/2007 S 3, and S/2009/S 1.
