Mean orbital speed for negligible mass' bodies


The orbital speed of a body, generally a planet, a natural satellite, an artificial satellite, or a multiple star, is the speed at which it orbits around the barycenter of a system, usually around a more massive body. It can be used to refer to either the mean orbital speed or the speed at a particular point in its orbit.
Mean orbital speed if one of the masses is almost negligible compared to the other mass is depended only on the mass of the greater body and the distance between the two bodies.
