Saturn, one of the eight planets in the solar system, is sixth in distance from the sun and second only to Jupiter in volume. And with Jupiter, Uranus and Neptune are gas (wood like) giant. In ancient China, it was also called Zhenxing or filling star.
Saturn is mainly composed of hydrogen, with a small amount of helium and trace elements. The inner core includes rock and ice, and the periphery is covered by several layers of metal hydrogen and gas. The outermost atmosphere is usually flat in appearance, although there are sometimes long-standing features. The wind speed of Saturn is as high as 1800 km / h, which is obviously faster than that on Jupiter. Saturn’s planetary magnetic field is between earth and the stronger Jupiter.
