Structure Foreign Saturn

The outside atmosphere Saturn is made of 96.7% hydrogen, 3% helium, methane and 0.2% ammonia 0.02%. In Saturn's atmosphere also contained little content acetylene, ethane and phosphine.

Clouds of Saturn, like Jupiter, spins at different speeds, depending on the position of latitude. Unlike Jupiter, Saturn is dark clouds and clouds of Saturn is greater at the equator. Cloud lower Saturn made by ice water, and a thickness of approximately 10 kilometers. Saturn is quite low temperature, with a temperature of 250 K (-10 ° F, -23 ° C). Cloud thereon, having a thickness of 50 kilometers is made of ice hidrogensulfida ammonium (chemical symbol: NH4HS) and the top of the cloud are ammonia ice clouds having a thickness of 80 km. The upper part is made of hydrogen and helium gas, wherein the thickness of approximately 200 to 270 km. Aurora is also known to form in the mesosphere Saturn. The temperature at the top of clouds Saturn are very low, amounting to 98 K (-283 ° F, -175 ° C). Temperatures within clouds Saturn larger than the outside because of the heat generated within Saturn. Winds of Saturn is one of the windiest in the solar system, reaching speeds of 500 m / s (1,800 km / h, mph 1118), which is much faster than the wind on Earth.

In the atmosphere of Saturn oval shaped clouds are also similar to the oval-shaped cloud, which is lighter in Jupiter. The point of this oval is a big storm, like a hurricane on Earth. In 1990, the Hubble telescope detects white cloud near Saturn's equator. The storm 1990 known as the white point giant Saturn storms are only unique within a short period of time and appeared every 39 years Earth time. Giant white spots are also found in 1876, 1903, 1933, and 1960. If this cycle remains constant, it is expected that in 2020, a large white spot will be formed again.

Voyager 1 probe detects hexagonal cloud near the north pole of Saturn around latitude 80 ° north. Cassini-Huygens confirmed later in 2006. Unlike the north pole, south pole shows no clouds hexagonal shape and attractive, Cassini discovered a storm similar to tropical cyclones in the South Pole is blocked with a wall of the eye clear. This discovery has the record, because there is no other planet in the solar system except Earth with the eyewall.
