11. Why does every planet have gravity
Why does every planet have gravity? Every planet has gravity, because EVERYTHING has gravity! Even you do! All matter in the universe has gravity. The bigger something is, the more gravity it has. The earth has strong gravity, but the sun is much bigger and has much stronger gravity. You also have gravity much, much, much smaller than the earth, so your gravity is very small. That's good or else things would be sticking to you!
