The '''argument of periapsis''' (also called '''argument of perifocus''' or '''argument of pericenter'''), symbolized as ''ω'', is one of the [[orbital element]]s of an [[orbit]]ing body.  Specifically, ''ω'' is the angle between the orbit's [[apsis|periapsis]] (the point of closest approach to the central point) and the orbit's [[ascending node]] (the point where the body crosses the [[plane of reference]] from South to North).  The angle is measured in the [[orbital plane (astronomy)|orbital plane]] and in the direction of motion.  For specific types of orbits, words such as "perihelion" (for [[Sun]]-centered orbits), "perigee" (for [[Earth]]-centered orbits), "periastron" (for orbits around stars) and so on may replace the word "periapsis".  See [[apsis]] for more information.

An argument of periapsis of 0° means that the orbiting body will be at its closest approach to the central body at the same moment that it crosses the plane of reference from South to North. An argument of periapsis of 90° means that the orbiting body will reach periapsis at its northmost distance from the plane of reference.

Adding the argument of periapsis to the [[longitude of the ascending node]] gives the [[longitude of the periapsis]].  However, especially in discussions of binary stars and exoplanets, the terms "longitude of periapsis" or "longitude of periastron" are often used synonymously with "argument of periapsis".

</ul>
In the case of [[equatorial orbit]]s (which have no ascending node), the argument is strictly undefined. However, if the convention of setting the longitude of the ascending node ''Ω'' to 0 is followed, then the value of ''ω'' follows from the two-dimensional case:
 
:<math> \omega = \arctan2({e_y}, {e_x})</math>  
 
:(if the orbit is clockwise (i.e. <math> ( \mathbf{r} \times \mathbf{v} )_z < 0</math>) then <math>\omega = 2 \pi - \omega\,</math>)
 
where:
 
*<math> e_x\,</math> and <math> e_y\,</math> are the ''x'' and ''y'' components of the eccentricity vector <math> \mathbf{e }.\,</math>
 
In the case of circular orbits it is often assumed that the periapsis is placed at the ascending node and therefore ''ω''=0.
