Geosynchronous Orbit (GEO)
Orbital distance from a planetary or other rotating body at which the orbital period matches the primary's rotational period. A satellite or other body placed at this distance remains near the same spot over the primary (over the equator). A geosynchronous orbit is circular and has zero inclination. There is only one geosynchronous orbit per celestial body.
