orbital velocity
  تندایِ مداری   
tondâ-ye madâri

Fr.: vitesse orbitale   

The velocity of an object in a given orbit around a gravitating mass. For a perfect circular orbit, the velocity is described by the formula V =√[G(M + m)/r], where G is the gravitational constant, M the mass of the primary gravitating body, m the mass of the orbiting object, and r the radius of the orbit.

→ orbital; → velocity.
