Question: how does earth move around?

Keywords: ,

  1. Great question. When the solar system formed, gravity was spinning it around like you on a merry-go-round. Eventually gravity brought clumps together to form the Sun, Earth, and the rest of the planets. After these were all created, we were still spinning, due to something called Angular Momentum, which keeps up moving in a circle. This creates a force which counter-acts the Sun pulling on us via gravity and keeps us in a stable orbit around the Sun. It is very similar to how you stay on a merry-go-round. It spins and pushes you out, but you are also moving fast and have a force acting towards the center to keep you on. If you didn’t have this force, you’d fly off 🙂
