“Mysterium Cosmographicum“ - Dan Phelps
KEPLER's Laws: 01_The orbit of a planet is an ellipse with the Sun at one of the two foci.
02_A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.
03_The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.
