Keplerian orbital velocity tondâ-ye madâr-e Kepleri Fr.: vitesse d'orbite képlérienne The velocity of an object orbiting another object according to → Kepler's laws. |
orbital velocity 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. |
