Johannes Kepler gave the Laws of Planetary Motion to the Western world.
His basic postulates are
1) The orbit of a planet is an ellipse, with the Sun as the focus of that ellipse
2) Planets move faster at perihelion and slowest at Aphelion
3) p1^2/p2^2 = a1^3 / a2^ 3, where p = period of revolution of the planet and a its semi major axis.
