Webt. e. An apsis (from Ancient Greek ἁψίς (hapsís) 'arch, vault'; PL apsides / ˈæpsɪˌdiːz / AP-sih-deez) [1] [2] is the farthest or nearest point in the orbit of a planetary body about its primary body. For example, for orbits about the Sun the apsides are called aphelion (farthest) and perihelion (nearest). WebIf a hemisphere is pointed towards the sun at perihelion, that hemisphere will be pointing away at aphelion, and the difference in seasons will be more extreme. This seasonal effect is reversed for the opposite hemisphere. Currently, northern summer occurs near aphelion.
