Orbital velocity, also known as circular orbital velocity, is the minimum velocity required by an object to remain in a stable circular orbit around a celestial body, such as a planet, moon, or satellite. It is the velocity at which the centripetal force (due to gravity) acting on the object is balanced by the object's inertia (centrifugal force), resulting in a stable, circular path.

The orbital velocity depends on the mass of the celestial body and the distance of the object from the center of the body. It can be calculated using the following formula:

Orbital Velocity (v) = √(G * M / r)
