This one is the fifth planet but the most gigantic. Like the next three is a gas giant but with mass two and a half times of all the other planets together. Ruler of planets, composed mostly of hydrogen and about 12% helium. On its surface the Great Red Spot is a gigantic storm lasting many centuries.

It has 63 moons, the larger one, Ganymede is bigger than Mercury.

Planet Saturn

Saturn is the sixth from the sun and second larger gas giant. Due to its mass the conditions on the planet are excessive. It has core of iron, is mostly made of liquid hydrogen and helium, and 9 spectacular rings made of dust, debris and ice.

Saturn is similar to Jupiter in materials, temperatures and satellites. On the surface a Great White Spot, a major storm appears every 30 years. It has 62 satellites. 1 Saturn year=30 earth years and 1 Saturn day= approximately earth 10 hours.
