Titan is Saturn's satellite
Titan is Saturn's satellite, the second largestThe solar system after Ganymede (Jupiter). In its structure, this body is very similar to the Earth. The atmosphere of it also has a resemblance to ours, and in 2008 a large underground ocean was discovered on Titan. For this reason, many scientists believe that this satellite of Saturn will become the abode of mankind in the future.
There are lakes, rivers and seas of Titan on Ethan andmethane, as well as high mountains, which consist mainly of ice. According to some scientists, around the stone core, which in diameter reaches 3,400 kilometers, there are several ice layers with different types of crystallization, and possibly also one layer of liquid.
Titan is a satellite whose atmosphere is thickreaches about 400 kilometers. It contains layers of hydrocarbon "smog". For this reason, the surface of a given celestial body can not be observed with the aid of a telescope.
Rotation and orbit
The radius of the orbit of Titan is 1221870kilometers. Outside, such satellites of Saturn as Hyperion and Iapetus, and inside - Mimas, Tethys, Dion, Enceladus. The orbit of Titan passes beyond the rings of Saturn.
The complete revolution around its planet Titan-satellite does for fifteen days, twenty-two hours and forty-one minutes. The speed of the orbit is 5.57 kilometers per second.
Like many others, Titan's satellite is relativelySaturn rotates synchronously. This means that the time of its rotation around the planet and around its axis coincide, as a result of which Titan is always turned one side to Saturn, therefore on the surface of the satellite there is a point at which Saturn always appears to be hanging at the zenith.
The slope of the rotation axis of Saturn provides a shiftseasons on the planet and its satellites. For example, last summer on Titan ended in 2009. At the same time, the duration of each season is about seven and a half years, since the complete revolution around the star Sun planet Saturn does for thirty years.
