(astronomy) The point, in an orbit about the Earth, that is closest to the Earth: the periapsis of an Earth orbiter.

Perigeenoun

The point, in an orbit about any planet, that is closest to the planet: the periapsis of any satellite.

Perigeenoun

The point, in any trajectory of an object in space, where it is closest to the Earth.

Perigeenoun

That point, in the orbit of the moon or other body orbiting the earth, which is nearest to the earth; - opposed to apogee. It is sometimes, but rarely, used of the nearest points of bodies not orbiting the earth, such as of a comet, a planet, etc. Called also epigee, epigeum.

Perigeenoun

periapsis in Earth orbit; the point in its orbit where a satellite is nearest to the Earth

Apogeenoun

(astronomy) The point, in an orbit about the Earth, that is furthest from the Earth: the apoapsis of an Earth orbiter.

Apogeenoun

The point, in an orbit about any planet, that is farthest from the planet: the apoapsis of any satellite.
