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.

Webrp = periapsis distance (for Earth perigee distance) ra = apoapsis distance (for Earth apogee distance) e = orbit eccentricity (0<1 for elliptic orbits, e = 0 is circular orbit) < = true anomaly Note that r is measured from the center of the Earth, hence we can note that: (1) where h = height above Earth’s surface WebThe main goal of this paper is to search for orbits that can be used in the Brazilian proposed Aster mission. This mission is under study and its objective is to use a spacecraft to observe the system 2001SN263, which is a triple asteroid system. With respect to the two-body problem (spacecraft and the main asteroid), the symmetries of the orbits are broken by … how fast do pygmy date palms grow

The point on an orbit which is closest to the orbited body is called the periapsis and the furthest point is the apoapsis. These points are indicated on the map view as "Pe" and "Ap", respectively. An orbit is considered “stable” if all points in the ...
