Saturn is the second largest planet in the solar system. It is the sixth planet from the Sun. Saturn was one of the most beautiful sites know to the Ancients. All Gas Giant planets that we know of have rings, but the rings on Saturn are more elaborate than any of the other planets. Galileo was the first person to actually see Saturn on a telescope in 1610. At first the planet confused him. Christian Huygens was the first person that correctly inferred the geometry of Saturn's rings.
In 1979, Pioneer 11 visited Saturn the first time. Later Voyager 1 and Voyager 2 visited it. In 2004, Cassini will arrive. The result of the rapid rotation and fluid state varies the diameter by 10%. It varies from 120,536 km in diameter to 108,728 km in diameter. Saturn's orbit is 1,429,400,000km (9.54 AU) from the sun. It is 5.68e26 kg in Mass. It is the least dense of the planets in the solar system.
Saturn is 75% hydrogen and 25% helium. It also has traces of water, methane, ammonia and rock. It is very similar to Jupiter. .
The Interior of Saturn in a rocky core. The two layers are a liquid metallic hydrogen layer as well as a molecular hydrogen layer. Various ices are present. The interior is extremely hot. It is about 12000k at the core. The energy that Saturn radiates is more than it receives from the sun.
Saturn has two prominent rings and one faint ring. The gap that's between the two prominent rings is called the Cassini division. The fainter gap is known as the Eneke division. The rings are composed of small particles that are each in independent orbit. They can be a centimeter to several meters in size. The rings on Saturn are very thin. Even though they are 250,000km in diameter, they are less than one kilometer thick. The rings are mostly water ice, but include rocky particles with icy coatings. .
Saturn's rings are as followed: D-Ring, Guerin Division, C-Ring, Maxwell Division, B-Ring, Cassini Division, Huygens Gap, A-Ring, Encke Minima, Encke Division, F-Ring, G-Ring, E-Ring.
