The Argument of Obliquity property of an object represents the orientation of the object's [
https: //en.wikipedia.org/wiki/Rotation_around_a_fixed_axis rotation ] axis around a reference axis determined by the [[Rotation Relative to]] property. If Rotation Relative to is set to the [[Simulation Grid]], this reference axis is the y-axis of the Simulation Grid. If Rotation Relative to is set to the Orbital Plane, the reference axis is the object's orbital axis, defined by its [[Inclination]] and [[Longitude of the Ascending Node]].
The Argument of Obliquity property is located in the Rotation section of the [[Motion]] tab of an object's properties panel.
Argument of Obliquity is defined in the range -180° to 180°, or -π to π rad.
