How you ever wonder what powers the nearest star from us, the sun! Well I think I know it's plasma. Plasma are made of molecules, the plasma molecules move really fast since it has a lot of energy. They are round and they are seperate from each other, they also collide with each other, each time they collide with each other they transfer energy to each other until they have the even amount of energy and the same temperature. This also shows why the sun is really hot and how does it keep us warm.
