Kepler three laws are as follows:
1: The orbit of a planet is an ellipse with the sun at one of the foci.
2: The line joining the planet and the sun sweeps equal areas in equal intervals of time.
3: The square of its period of revolution around
the sun is directly proportional to the cube of the mean distance of a planet from the sun.
