In celestial mechanics, the argument of latitude (<math> u </math>) is an angular parameter that defines the position of a body moving along a Kepler orbit. It is the angle between the ascending node and the body.


It is the sum of the more commonly used true anomaly and argument of periapsis.

<math> u = \nu + \omega </math>

where <math> u </math> is the argument of latitude, <math> \nu </math> the true anomaly, and <math> \omega </math> the argument of periapsis.
