(1) All planets, with the Sun as one of the foci, move about the Sun in elliptical orbits.
(2) A radius vector that is joining any planet to the Sun covers equal areas in equal
(3) The squares of the periods of revolution of all planets are directly proportional to the
cubes of their mean distances from the Sun.
