what is the equation for orbital speed. The orbital speed of planets and satellites can be calculated by the following equation. The orbital velocity can be found using the formula.

Where G is the gravitational constant m is the mass of the central body in this case Earth and r is the distance from the satellite to Earths center in meters. 6371 km 400 km 6771 km. Orbital Period Definition An orbital period is defined as the total time it takes a satellite or orbiting object to make one complete rotation around another larger object.
Orbital speed square root gravitational constant mass of the attractive body radius of the orbit.
6371 km 400 km 6771 km. 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. This is the vis-viva equation and is more generally. Doing a little algebra we get which gives the objects speed at any point along the orbit.
