The Orbital Velocity Of An Artificial Satellite In A Circular Orbit

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. In space gravity supplies the centripetal force that causes satellites like the moon to orbit larger bodies like the earth. V orbital r. For a satellite orbiting at an altitude of half 1705911. Orbital velocity velocity sufficient to cause a natural or artificial satellite to remain in orbit inertia of the moving body tends to make it move on in a straight line while gravitational force tends to pull it down.

The term can be used to refer to either. The height h of the satellite above the earth s surface is take radius of earth as r e. Here you get a set of orbital velocity expressions that are derived in this post. The orbital velocity of an artificial satellite in a circular orbit just above the centre s surface is v.

By steven holzner. V orbital gm r 1 2. In gravitationally bound systems the orbital speed of an astronomical body or object e g. You can visit our post on quick listing and descriptions of these satellite velocity expressions.

An artificial satellite is moving in a circular orbit around the earth with a speed equal to half the magnitude of the escape velocity from the earth. The orbital path elliptical or circular thus represents a balance between gravity and inertia.
