Kepler's third law of planetary motion, also known as the cycle law, states that all planets orbit the Sun as a Focal point ellipse, The ratio of the ellipse orbital semi-macroaxis cube and cycle square is one constant. Commonly used in ellipse orbital Calculator.

Kepler's third law of planet motion

Satellite orbit cycle
T = sqrt(4*PI²*r³/GM)

Here

G = gravitational constant number = 6.6726 x 10 ¹¹ N - m ² / kg ²

r = Satellite orbit average radius

M = Satellite Quality
