Orbital Velocity Formula

The orbital speed / orbital velocity is defined as the the speed at which any rotating object such as planets, satellites orbits around the barycenter of a system, usually around a more massive body. Earth's mean orbital speed is the average speed at which the Earth revolves around the sun. Find here the orbital velocity formula to find the orbital speed.

Orbital Speed Formula

Formula :

Orbital speed =2 x ∏ x a / T


a = semimajor axis length
T = Orbital period
