Orbital velocity, velocity sufficient to cause a natural or artificial satellite to remain in orbit.
Inertia of the moving body tends to make it move on in a straight line, while gravitational force tends to pull it down. The orbital path, elliptical or circular, thus represents a balance between gravity and inertia.
The minimum velocity required to move around another body is known as minimum orbital velocity.
The equation used for calculating the orbital velocity can be written as: where refers to the mass at the central body, is the constant given as , is the radius of the orbit of the satellite.
