General Information About Saturn

This planet is more than any other giant planets like Jupiter. Its mass is 95 times, and the equatorial radius (60,370 km) in 9,5 times higher than the earth, and compression of 1:10, ie, the polar radius of 8.5 times Earth’s. Acceleration of gravity on Saturn in 1.15 times the earth, and the critical speed is 37 km / sec. The axis of rotation of the planet is tilted at an angle of 26 ° 45 ‘, and if it is by its nature was like on Earth, and was much closer to the sun, then it would be alternated with seasons of the year. But the structure of Saturn is the same as that of Jupiter, and it also rotates the zonal with periods of 10h 14m (equatorial belt), and in 10h 39m (temperate zones).

But the structure of Saturn is the same as that of Jupiter, and it also rotates the zonal with periods of 10h 14m (equatorial belt), and in 10h 39m (temperate zones). On the structure of the gaseous planet, and it shows a small average density equal to 0.69 g/cm3, ie, figuratively speaking, if Saturn was in the water, he would have sailed on its surface. Because of the smaller (in comparison with Jupiter) mass pressure in the depths of Saturn is growing more slowly, and, apparently, a layer of liquid hydrogen in a mixture with helium begins at a depth equal to half the planet’s radius, where the temperature is 10000 ° C and pressure – 3-109 hPa (3-106 bar).. Below, at a depth of 0,7-0,8 radius, there is, a layer of metallic phase of hydrogen, electric currents which generate the planet’s magnetic field, and under this layer is molten silicate-metallic core, whose mass is 9 times greater than the mass of Earth, or nearly 0.1 mass of Saturn.

Saturn receives from the sun 92 times less energy than the Earth, in addition, 45% of the energy it reflects. Therefore, the temperature of its upper layers should be about -190 ° C, but it is close to -170 ° C. The reason is that from the hot bowels of the planet comes into heat twice more than the Sun. Saturn’s radio emission is relatively small, which indicates the presence of an external magnetic field and radiation belt, which is weaker than that of Jupiter. This was confirmed by automated probe Pioneer 11, which is September 1, 1979 flew at a distance of 21,400 km from the surface of Saturn and discovered its magnetic field, whose axis almost coincides with the axis of rotation of the planet. The radiation belt consists of several bands separated by wide cavities that do not contain electrically charged particles. Saturn has two moons – they photographed the probe “Cassini”. The fact that such small planets (3 and 4 km in diameter) have survived until now means that small comets, which are usually threatened by them, are found in the solar system is not so often. Total number of satellites in the sixth planet is now 33, with widths from 34 to 5150 km. Like Jupiter, these satellites are numbered according to the sequence of their discovery.
