eli5 : How does the earth not collide with the sun when orbiting
In: 0
Well, the earth is moving at such speed at a constant distance (in planetary scale) from the sun that its gravity pull doesn’t have enough time to act fast enough to pull Earth in. It’s only when Earth starts slowing down that the sun has time to pull on us and when that happens the earth picks up speed very quickly again and keeps the orbit.
This is a constant dance between stars, planets, moons, etc..
