• Longitude of the ascending node — The longitude of the ascending node (☊ or Ω) is one of the orbital elements used to specify the orbit of an object in space. It is the angle from a reference direction, called the origin of longitude , to the direction of the ascending node,… …   Wikipedia

• Longitude of the periapsis — In astrodynamics, the longitude of the periapsis (symbolized varpi) of an orbiting body is the longitude (measured from the point of the vernal equinox) at which the periapsis (closest approach to the central body) would occur if the body s… …   Wikipedia

• Node — In general, a node is a localised swelling (a knot ) or a point of intersection (a vertex). Node may refer to: In mathematics Node (autonomous system), behaviour for an ordinary differential equation near a critical point Node (graph theory), a… …   Wikipedia

• Orbital node — The ascending node. An orbital node is one of the two points where an orbit crosses a plane of reference to which it is inclined.[1] An orbit which is contained in the plane of reference (called non inclined) has no nodes …   Wikipedia

• Mean longitude — In astrodynamics or celestial dynamics, mean longitude is the longitude at which an orbiting body could be found if its orbit were circular, and free of perturbations, and if its inclination were zero. Both the mean longitude and the true… …   Wikipedia

• True longitude — In astrodynamics true longitude is the longitude at which an orbiting body could actually be found if its inclination were zero. Together with the inclination and the ascending node, the true longitude can tell us the precise direction from the… …   Wikipedia
