Orbital Velocity
The speed and direction a satellite is moving at any point in its orbit, crucial for keeping it in space without falling or escaping.
TECHNICAL DEFINITION
Orbital Velocity is the vector quantity representing both the instantaneous speed and direction of an orbiting body relative to its primary, essential for maintaining a stable trajectory and determined by the body's position and the gravitational field.
