The Sun is the center of what we go around , and did you know that the sun is not a planet it's actually a star. Also did you know that in the next 5 million or billions of years the sun will run out of gas and become the size of the earth but after that it will expand big and eat mercury, Venus, earth, mars, Jupiter, Saturn and maybe Uranus, oh and the moon.To fill the sun with earths all the way you need about 100,000,000 that's crazy can you imagine 1 million earths. The sun is super hot like nothing that you can think of sun=heat=5,750
