Argument of periapsis - Wikipedia

An apsis 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). See more There are two apsides in any elliptic orbit. The name for each apsis is created from the prefixes ap-, apo- (from ἀπ(ό), (ap(o)-) 'away from') for the farthest or peri- (from περί (peri-) 'near') for the closest point to the See more The perihelion (q) and aphelion (Q) are the nearest and farthest points respectively of a body's direct orbit around the Sun.

The latter may be pronounced with an ah vowel ( / t[invalid input: 'ᵻ']ˈtɑːniən / ), but the form for Titan is only pronounced with an ay vowel: / taɪˈteɪniən /.

WebArgument of periapsis (ω) — Orientation of the ellipse in the orbital plane, as an angle measured from the ascending node to the periapsis. True Anomaly (v) — Position of the orbiting body along the ellipse at a specific time. The satellites position on the path is measured counter-clockwise from periapsis and is called the true anomaly, ν.
