Kepler's First Law states

• objects attract other objects with a force that is directly proportional to the product of their masses

• the square of the ratio of the periods of any two planets revolving around the Sun is equal to the cube of the ratio of their average distance from the Sun

• An imaginary line joining a planet and the sun sweeps out an equal area of space in equal amounts of time.

• Planets move about the Sun in an elliptical orbit with the Sun at one of the foci.
