The outer planets

I'm back with another blog about space and our solar system. I'm going to talk about the outer planets. I will tell the similarities and differences about the outer planets. I'll even tell you what they are made out of and their type of atmosphere and structure and more.

The outer planets are similar because they are the four farthest planets from the sun.   They are different from each other because of their size and color. They are made out of gases like hydrogen and helium that's why they are called the gas giants.The planets have thick gases and liquid layers covering a small solid layer.

 

 Jupiter is the largest planet in the solar system and more than twice the mass of all the other planets combined. The atmosphere on Jupiter is 90% Carbon dioxide and 10% Helium and is about 1000 km or 100,000,000 cm deep. The Great Red Spot is a huge storm full of swirling gases and could fit two earth's in it. Jupiter's outer layer is made out of hydrogen and helium. The inner layer is made out of liquid metallic and has a rocky core.
 





Saturn's atmosphere is made out of 75% hydrogen and 25% helium. Saturn has other substances like ice and methane gas. Saturn is almost entirely made out of gas and it's atmosphere is a couple hundred miles deep. The outer layer is made out of hydrogen and the inner layer is made out of liquid metallic hydrogen and covers a rocky or icy core. Saturn does not have so much mass so if you put Saturn on a lake it would float.
 



The atmosphere of Uranus is made out of methane gas and when you see Uranus it looks bluish or greenish color because of the methane gas. The gas absorbs the red light from the sun which gives it the color. Uranus is made out of ice to so that's why some people call it the ice giant. The interior of Uranus is made out of methane ice and  covers a icy or rocky core. Scientist believe that a big object hit Uranus and caused it to rotate on the side.
