Editing Argument of Obliquity

The Argument of Obliquity property of an object represents the orientation of the object's [[wikipedia: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]].

When the Argument of Obliquity is zero and the [[Obliquity]] is 90°, the object's rotation axis will lie in the reference plane, pointed in the direction of the positive x-axis of the Simulation Grid (if Rotation Relative to is set to the Simulation Grid) or the direction of the orbit's [[Apocenter Distance|apocenter]] (if Rotation Relative to is set to the Orbital Plane). Non-zero Argument of Obliquity values represents how far the rotation axis is rotated from this direction.

When the Obliquity of an object is zero, its Argument of Obliquity is undefined and this property will be '''read-only'''.

==Property Details==

===Location===

The Argument of Obliquity property is located in the Rotation section of the [[Motion Tab|Motion]] tab of an object's properties panel.

===Units===

Argument of Obliquity is an angle, and can be viewed or edited using the following units:

* Radians (rad)
* Degrees (°) = (180/π) rad

Argument of Obliquity is defined in the range -180° to 180°, or -π to π rad.

−	The Argument of Obliquity property of an object represents the orientation of the object's [[wikipedia:Rotation_around_a_fixed_axis\|rotation axis]] around a reference axis determined by the [[Rotation Relative to]] property.
