1) The law of orbits. This is when all planets move in elliptical orbits, with the sun at once focus.
2) The law of areas. A line that connects a planet to the sun sweeps out equal areas in equal times.
3) The law of periods. The square of the period of any planet is proportional to the cube of semimajor axis of its orbit.
These laws were derived for orbits around the sun, but they apply to satellite orbits also. I hope this helps! ~Mia
