Saturn has many satellites, maybe about 200, of which more than 80 have confirmed orbits.
Observations through the Hubble Space Telescope (HST) and photos sent by Voyager have shown various bodies near Saturn that could be new moons. The long journey of the Cassini probe through the Solar System has also paid off.
In general, the density of saturn satellites It is very low and also reflect a lot of light. This suggests that the most abundant matter is frozen water, almost 70%, and the rest are rocks.
The satellite system around Saturn shows some interesting examples of orbital dynamics, such as shepherd satellites, coorbital satellites and Trojan satellites. In addition, some Saturn satellites are in resonance with each other.
The following table shows some of the most important satellites ordered by their distance from the planet.
|Saturn Satellites||Radius (km)||Distance (km)|
Titan It is the largest of Saturn's satellites and the second largest in the entire Solar System, with a diameter of 5,150 km.
Titan has a denser atmosphere than Earth's, formed by nitrogen and hydrocarbons that give it an orange color. It turns around Saturn to 1,222,000 km, in just under 16 days.
Rea It is 1,530 km in diameter and turns 527,000 km from Saturn every four and a half days. It has a small rocky core. The rest is an ocean of icy water, with temperatures ranging from 174 to 220 ° C below zero.
The craters caused by meteorites do not last long, because the water turns to freeze and erases them.
Jápeto or Iapetus It is one of the strangest Saturn satellites. It has a density similar to that of Rhea, but its appearance is very different, because it has a dark and a clear face. The dark face is probably the material of an ancient meteorite. Its diameter is 1,435 km and it turns very far, 3,561,000 km from Saturn in 79 days and a third.
Dione and Tethys They are two other large Saturn satellites that have close orbits and similar sizes. Dione is 1,120 km in diameter, while Tethys is 1,048. The first tour at 377,000 km and the second at 295,000.
