mechanics, the longitude of the periapsis, also called longitude of the pericenter, of an orbiting body is the longitude (measured from the point of the vernal...

terms "longitude of periapsis" or "longitude of periastron" are often used synonymously with "argument of periapsis". In astrodynamics the argument of periapsis...

angles of inclination, longitude of the ascending node, and argument of periapsis can also be described as the Euler angles defining the orientation of the...

328°±51°.: 67  The longitude of periapsis is the sum of the ascending node and argument of periapsis, so subtracting Vanth's ascending node of 53.49°±0.33°...

of periapsis, so subtracting Dysnomia's ascending node of 126.17°±0.26° from its longitude of periapsis gives 180.83° for its argument of periapsis. Dysnomia's...

so-called longitude of the periapsis (also called longitude of the pericenter). For the orbit of the Earth, this is called the longitude of perihelion...

true anomaly, ϖ ≡ ω + Ω is the longitude of orbit's periapsis, ω is the argument of periapsis, and Ω is the longitude of the orbit's ascending node, Multon...

The longitude of the ascending node (symbol ☊) is one of the orbital elements used to specify the orbit of an object in space. It is the angle from a specified...

body will be at periapsis. If this is less than planet's radius an impact should be expected. The distance of closest approach, or periapsis distance, is...

Mean longitude is the ecliptic longitude at which an orbiting body could be found if its orbit were circular and free of perturbations. While nominally...
