Calculate the speed of an orbiting body.

Orbital velocity is the speed required for an object (like a satellite or moon) to remain in a stable circular orbit around a central body (like a planet or star). Our free Orbital Velocity Calculator uses Newton's law of universal gravitation to instantly compute this speed. By inputting the mass of the central body and the radius of the orbit, you can determine how fast a satellite needs to travel to avoid falling back to the surface or escaping into deep space.
v = โ(G ร M / r)
Where G is the gravitational constant (6.674 ร 10-11 Nยทmยฒ/kgยฒ), M is the mass of the central body, and r is the orbital radius.
