	The equivalent of [[apoapsis]] of a body in [[Earth ortbit]], i.e. the point where it is furthest from the Earth, is called its '''apogee''' or '''apogee height'''.		The equivalent of [[apoapsis]] of a body in [[Earth ortbit]], i.e. distance to the point where it is furthest from the Earth, is called its '''apogee''' or '''apogee height'''.

	Unlike with all other bodies, mission planners are usually more interested in the height above the surface for [[low Earth orbit]] spacecraft. Hence apogee height refers to the distance between the body and the Earth's surface rather than the distance between the body and the Earth's centre of mass, for all objects in Earth orbit.<ref name=Wertz>J.R. Wertz - ''Orbits and astrodynamics'' in J.R. Wertz, D.F. Everett & J.J. Puschell eds.

	If you wish to anambiguously use the same measurements as with all other bodies, it is best to say [[apofocus distance]] rather than apogee.		If you wish to anambiguously use the same measurements as with all other bodies, it is best to say [[apofocus distance]] rather than apogee.
