Planets {Saturn, planet} can be sixth nearest to Sun and second-largest planet.
properties
Diameter is 121,000,000 meters. Mass is 95 times Earth mass. Density is 0.7 g/cm^3, because it is 66% hydrogen. Gravity is 1.14 times Earth gravity.
properties: rotation
Saturn rotates every 10 hours on axis tilted 27 degrees to orbit.
properties: temperature
Surface temperature is -170 C.
properties: orbit
Saturn is 1,427,000,000,000 meters from Sun. Circular orbit of 29.5 years slightly inclines to ecliptic.
layers
Core is rock, 20,000,000-meter diameter. Around core is ice 5,000,000 meters thick. Around ice layer is metallic hydrogen 8,000,000 meters thick. Around that layer is molecular hydrogen.
atmosphere
Atmosphere is like Jupiter. Saturn has yellow and green belts. Perhaps, dark particles in atmospheres of Saturn, Titan, and Jupiter are polymers.
moons
Saturn has 10 moons. Titan is largest moon, with diameter 5,000,000 meters. It is the only moon with atmosphere, mainly nitrogen, and has opaque red methane and hydrogen clouds. It has rock core, wet water and ammonia mantle, and ice crust. Surface temperature is -180 C.
Iapetus has surface organic material. Enceladus has diameter 504 kilometers, has rocky core, has icy surface, has liquid water under surface, has tidal forces, makes water jets from south-pole plain that add water to E-ring, and has organic compounds. Other main moons, from inner to outer, are Prometheus, Epimetheus, Pandora, Janus, Mimas, Enceladus, Tethys, Dione, and Rhea.
rings
Rings of ice crystals and ice-coated dust 1-centimeter diameter are from 15,000,000 to 79,000,000 meters. Rings are 0.1 to 16,000 meters thick. Outer E-ring goes from Mimas to between Dione and Rhea.
