Saturn - the sixth in distance from the Sun and the second largest planet in the solar system. Saturn is rapidly rotating around its axis ( with a period - 10.23 hours), consisting mainly of liquid hydrogen and helium, has a thick layer of the atmosphere . Saturn orbits the Sun at 29.46 Earth years at an average distance of 1,427,000,000 km. The equatorial diameter of the upper boundary of clouds - 120 536 km , polar and a few hundred kilometers less [citation needed ]. In the atmosphere of Saturn contains 94 % hydrogen and 6 % helium (by volume ). His weight at 95 times the mass of Earth , the magnetic field powerful than a thousand times . It is believed that Saturn has a small core of silicates and iron , covered with ice and a deep layer of liquid hydrogen. In 2013 of the existence of 62 natural satellites of Saturn , the largest of which - Titan.
Unlike Jupiter, Saturn bands reach very high latitudes - 78 degrees. There is a huge oval formation of Earth-sized , located near the north pole , called the Great White stain revealed a few spots smaller. After more than Jupiter flow rate, these hurricane vortices quickly fade and mixed with stripes. Speed ​​zonal winds near the equator reach 400-500 m / s and at a latitude of 30 degrees - about 100 m / s. The low contrast colors on the visible disk of Saturn is the fact that because of the low temperatures in the transcendental atmosphere of Saturn, where ammonia vapor vymorozhuyutsya , a layer of thick fog that hides the structure of the belts and zones on Saturn because they are not as clearly visible as in Jupiter.
Saturn has a prominent system of rings , consisting mostly of ice particles , fewer heavy elements and dust. Around the world turns 62 known at this time ( 2013) satellites. Titan - the largest among them, is the second largest moon in the Solar System (after Jupiter's moon , Ganymede ), which is superior in size and Mercury is unique among the satellites in the solar system a dense atmosphere.
There are currently orbiting Saturn is automatic interplanetary station " Cassini ", launched in 1997. She went to the Saturn system in 2004. Its task is to study the structure of the rings , as well as the dynamics of the atmosphere and the magnetosphere of Saturn.
