Apsis: Art, Perihelion and aphelion & Terminology

An apsis (from Ancient Greek ἁψίς (hapsís) 'arch, vault' (third declension); pl. apsides /ˈæpsɪˌdiːz/ AP-sih-deez) is one the two extreme points in the orbit of a planetary body about its primary body, either the farthest point (apoapsis) or the nearest point (periapsis). The line of apsides (also called apse line, or major axis of the orbit) is the line…
