Kepler's Third Law (Cycle Law) Calculator
Kepler's third law of planetary motion, also known as the periodic law, refers to all planets orbiting an elliptical orbit with the sun as the focus. The ratio of the cube of the semi-major axis of the elliptical orbit to the square of the period is one. constant. Often used in the calculation of elliptical orbits.

Satellite orbital period
\( T = sqrt(4 \times PI^2 \times r^3/GM) \)
Here
G = gravitational constant = 6.6726 x 10<sup>-11</sup>N-m<sup>2</sup>/kg<sup>2</sup>
r = average radius of the satellite orbit
M = satellite quality
