The Star of the Solar System and The Leader of the Planet Pals The Sun is more than just a star, she's the leader of the Planet Pals. She doesn't know why Earth loves her. She thinks because she keeps him warm and help grow different food or plants. She's 4 and a half billion years old and is made out of hydrogen and helium. She's really big, that she can fit a million Earths and a thousand Jupiters inside of her. If you try and stare at her, it's barely impossible to put on some sunglasses.
