Newtons third law explains how there is a gravitational force between two objects. The distance between the two objects explains the mass that is necessary for one object to keep the second object at a constant orbital speed. The suns mass is about 333,000 times the mass of Earth. By using Keplers and Newtons discoveries we can find the mass of just about anything....
