Geocentric orbit refers to the orbit of any object orbiting the Earth, such as the Moon or artificial satellites. Orbital revolution is the cyclical path taken by one object around another object (or point, line, etc. ... Earth (often referred to as the Earth, or the earth), is the third planet in the solar system in terms of distance from the Sun, and the fifth largest. ... Bulk composition of the moons mantle and crust estimated, weight percent Oxygen 42. ... For other uses, please see Satellite (disambiguation) A satellite is an object that orbits another object (known as its primary). ...

### Circular Orbits

The speed (v) of a satellite in circular orbit around the earth is:
Where G is the universal gravitational constant or
Where M is the mass of the combined planet/satellite system. The earth's mass is .
And where r is the radius of the orbit measured from the planet's center.

In astrodynamics or celestial mechanics a circular orbit is an elliptic orbit with the eccentricity equal to 0. ...

 Geocentric pointing three-axis stabilised satellite in low orbit with single-axis steerable solar generator - Patent ... (3132 words) The invention concerns a geocentric pointing three-axis stabilized satellite configuration for any orbit (possibly heliosynchronous, preferably but not necessarily steeply inclined and/or of low altitude); it is more particularly directed to the location and the kinetics of its solar generator. This kind of orbit considerably simplifies the problems of orienting the solar generator: a single rotation axis is sufficient to maintain the cells perpendicular to the Sun at all times. Depending on the geocentric stabilization mode adopted, the satellite may or may not retain a fixed attitude relative to the geocentric direction and the orbit.
