Periareion
Definition
The closest distance that a body in Mars orbit comes to Mars, i.e. the periapsis of a body in Mars orbit.
The greatest distance from Mars is known as Apoareion.
Unlike perigee, other apsides such as periareion and perilune are measured from the center of mass and not the surface of the body.[1]
