** Kepler's 3 rd Law: P 2 = a 3 Kepler's 3 rd law is a mathematical formula**. It means that if you know the period of a planet's orbit (P = how long it takes the planet to go around the Sun), then you can determine that planet's distance from the Sun (a = the semimajor axis of the planet's orbit) Kepler's Third Law says P2 = a3: After applying Newton's Laws of Motion and Newton's Law of Gravity we nd that Kepler's Third Law takes a more general form: P2 = 4ˇ2 G(m1 +m2) # a3 in MKS units where m1 and m2 are the masses of the two bodies. Let's assume that one body, m1 say, is always much larger than the other one. Then m1 + m2 is nearly equal to m1. We can then use our technique o

Planets do not move with a constant speed, but the line segment joining the sun and a planet will sweep out equal areas in equal times Kepler's Third Law for Earth Satellites. The velocity for a circular Earth orbit at any other distance r is similarly calculated, but one must take into account that the force of gravity is weaker at greater distances, by a factor (RE/r)2.
