Planet moon artificial satellite spacecraft or star 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 orbital velocity of an artificial satellite in a circular orbit.
The orbital velocity of an artificial satellite in a circular orbit just above the centre s surface is v.
And for nearby orbit.
In space gravity supplies the centripetal force that causes satellites like the moon to orbit larger bodies like the earth.
V orbital gm r 1 2.
Also there is also a post on the definition or explanation of this velocity.
V orbital r.
In gravitationally bound systems the orbital speed of an astronomical body or object e g.

The orbital path elliptical or circular thus represents a balance between gravity and inertia.
Thanks to physics if you know the mass and altitude of a satellite in orbit around the earth you can calculate how quickly it needs to travel to maintain that orbit.
You can visit our post on quick listing and descriptions of these satellite velocity expressions.
Here you get a set of orbital velocity expressions that are derived in this post.
The height h of the satellite above the earth s surface is take radius of earth as r e.
The term can be used to refer to either.
