kepler's third law of planetary motion, also known as the periodic law, refers to the ratio of the cube of the semi-major axis of the elliptical orbit to the square of the period for all planets orbiting an elliptical orbit with the sun as the focus. constant. often used in the calculation of elliptical orbits.
kepler's third law of planetary motion
satellite orbital period
T = sqrt(4*PI2*r3/GM)
here
g = gravitational constant = 6.6726 x 10-11N-m2/kg2
r = average radius of satellite orbit
m = satellite mass
