Q: Why does the Earth orbit the Sun?

Does this occur due to centripetal force and the lack of friction to stop the Earth from spinning? Physicist: I’ll break this down into two questions: “Where does the rotation originally come from?” and “Once the a planet is in orbit, what keeps it there?”Where does the rotation originally come from? : The original yearly rotation of the Earth around the Sun (orbital rotation), as well the daily rotation of the Earth about it’s own axis (just “rotation”) is essentially dumb luck. : Gravity pulls the Earth in, and centrifugal force holds it out. * The centrifugal force on the Earth is just a result of the Earth moving in a curved path around the Sun.
