The Longitude of the Ascending Node, Ω, represents the angle between the orbit's ascending node and a reference direction. Source: Wikimedia Commons
The Longitude of the Ascending Node of an object's orbit is the angle between the orbit's ascending node (the point where the object crosses from below some reference plane to above the reference plane) and a reference direction. In Universe Sandbox, the reference plane is the x-z plane of the Simulation Grid, and the reference direction is the negative x-axis.
For an object orbiting in the reference plane (with an Inclination of zero), the Longitude of the Ascending Node will be undefined and the property will be read-only.
Longitude of the Ascending Node is one of six orbital elements that describe an object's orbit.

Location[ | ]
The Longitude of the Ascending Node property is located in the Orbital Elements section of the Motion tab of an object's properties panel, if that object has an Orbital Parent.
Units[ | ]
Longitude of the Ascending Node is an angle, and can be viewed or edited using the following units:
- Radians (rad)
- Degrees (°) = (180/π) rad
Longitude of the Ascending Node is defined in the range 0-360°, or 0-2π rad.
