Phrases with «orbital velocity»

Orbital velocity refers to the speed at which an object needs to move in order to stay in orbit around a planet, moon, or another celestial body. It is the perfect balance between the pull of gravity and the forward speed of the object. If the object moves too slowly, it will fall back to the body; if it moves too fast, it will escape or move away from the body. Orbital velocity allows objects to maintain a stable path around a larger celestial object. Full definition
