Answer:
In gravitationally bound systems, the orbital speed of an astronomical body or object is the speed at which it orbits around either the barycenter or, if one object is much more massive than the other bodies in the system, its speed relative to the center of mass of the most massive body.
The expression / formula for orbital velocity is -
u= 2πa/T
Here -
u is orbital velocity
a is the length of the semimajor axis in meters and
T is the orbital period .
