3. Johannes Kepler An achievement of Kepler's would be Kepler's Three Laws of Planetary Motion. The first law is the orbit of every planet is an ellipse with the Sun at one of 2 foci. The second law is a line joining a planet and the Sun sweeps out equal areas during intervals of time. Lastly the square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.
