The Sun is the dwarf star[1] at the center of the Solar System. There are eight major planets and other celestial bodies orbiting it.[2] It is extremely hot, with surface temperatures in excess of 6,000 K and a central core temperature of about 15,700,000 K.[3] Since the Sun is about 150,000,000 kilometers away,[1] only a very small amount of its heat and light reach the Earth. By contrast, the Earth's Moon is very much smaller and very much colder.[4]
