Earth, Moon, and Sun Gravity and Motion Isaac Newton was the first scientist to explain what keeps the Earth and Moon in orbit Force – a push or a pull There is a force acting between the Earth and the moon that keeps them in orbit Astronomers use light years since the distances in space are so large that, if expressed in km or m, the numbers would be mind boggling..
