Sunis a hot shot full of energy! Sun is located at the very center of the Solar System. No wonder he has such a big ego, but who can blame him? The whole solar system literally revolves around him! Im a real hottie! The temperature at my center is a sizzling 28,500 F, and on my surface it is 10,340 F. I am the star located at the center of your Solar System, but I am just one of an estimated 200-400 billion stars orbiting within our Milky Way Galaxy. There may be as many as 200 billion galaxies, which means that your Sun is only one out of 80,000,000,000,000 stars! I am composed mostly of hydrogen and helium with trace amounts of other elements. All my energy is produced in my core by nuclear fusion. This energy travels to the surface and is then emitted as visible light, which reaches the Earth, 93,000,000 miles away, about 8 minutes later, and as the heat that keeps our planet warm..
