Perigee
For an object orbiting the Earth (or, since the Interplanetary Age, for any planet), the perigee is the point in each orbit which is closest to the primary. The perigee generally varies a small amount from orbit to orbit. The closest perigee is called the proxigee. The opposite term is apogee.
