Longitude of the ascending node

The longitude of the ascending node (bright green) as a part of a diagram of orbital parameters.

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 reference direction, called the origin of longitude, to the direction of the ascending node (☊), as measured in a specified reference plane.[1] The ascending node is the point where the orbit of the object passes through the plane of reference, as seen in the adjacent image.
