Well, orbital velocity is the velocity with which a body or a satellite revolves along a circular orbit around the earth. The expression for orbital velocity is,
From the expression, since G, gravitational constant, and M, mass of the earth, are constants,
This means the orbital velocity depends on the orbital radius of the satellite but not on the mass of the satellite. From the relation, we thus form an equation,
