Everything about Perigee totally explained
:
This is about the orbital parameter. For the quarterly publication, see .
Perigee is the point at which an object in
orbit around the
Earth – either the
Moon or a spacecraft, satellite, or other body – makes its closest approach to the Earth. Often the term is used in a broader sense to define the point in an orbit where the orbiting body is closest to the body it orbits.
The
Greek prefix "peri" means close or near. The suffix "gee", derived from
Gaea, means Earth.
Perigee is part of the broader family of
apses, astronomical terms which denote distances of orbiting bodies. Since all orbits are elliptical, each orbit contains both a nearest point and a farthest point.
