(1) Law of orbits
(2) Law of areas:
(3) Law of periods
Kepler's three laws of planetary motion are described as follows: :
1)
Law of orbits: All planets move in elliptical orbits having the Sun as one focus.
2)
Law of areas: A line or radius vector $r(t)$ or a line segment that connects any planet to the sun sweeps out equal areas in equal time.
3)
Law of periods: The square of the orbital period of any planet is proportional to the cube of the semi-major axis of its orbit.
