Apogee

Scheme of the orbit of a body around a planet (3). Point 1 is the apogee and point 2 the perigee.

Apogee (from the Greek ἀπό 'apart, far from' and γεω- 'terrestrial, relative to planet Earth') is the point in an elliptical orbit around the Earth in which a body is furthest from its center. The closest opposite orbital point is called perigee.

A body in elliptical orbit around another of greater mass moves at the minimum orbital speed when it is in its apoastrum (apogee for a body in orbit around the Earth) and at the maximum orbital speed when it is in its periastrum (perigee for a body in orbit around the Earth) because, according to Kepler's second law, the body sweeps equal areas in equal times in its path through the ellipse.
