orbital velocity
Circling space pace
Orbital velocity is the speed an object must travel to remain in stable orbit around a larger body.
At this speed, the object's forward momentum precisely balances gravitational pull, creating continuous free fall without ever hitting the surface: The rocket needs to reach orbital velocity to enter a stable orbit.
Different altitudes require different orbital velocities—closer orbits demand higher speeds.
