Johannes Kepler, developed three laws which described the motion of the planets across the sky.

1. The Law of Orbits: All planets move in elliptical orbits, with the sun at one focus.

2. The Law of Area : A line that connects a planet to the sun sweeps out equal areas in equal times.

3. The law of period: The square of the period of any planet is proportional to the cube of the semimajor axis of its orbit.
