Question

Given that earth travels through space at a rate of 67,000 miles per hour, why didn’t it move away from the Apollo 11 astronauts when they left earth orbit?

In: Physics

Answer 1

Moon is on Earth orbit, remember. So on this large Earth-centered system of mass that orbits Sun, all Apollo 11 astronauts did was change their place within that system.
