	~~In [[celestial mechanics]]~~, ~~'''true anomaly'''~~ is ~~an angular [[parameter]] that defines the position of~~ a ~~body moving along a [[Keplerian orbit]]~~. ~~It is the angle between the direction of [[periapsis]] and the current position of the body,~~ as ~~seen from the main focus of the [[ellipse]] (the point around which the object orbits)~~.

	~~The true anomaly is usually denoted by the [[Greek alphabet\|Greek letters]] <math>\,\nu~~<~~/math~~> or <~~math>\,\theta</math>, or the [[Latin script\|Latin letter]] <math> f </math~~>.

	The ~~true anomaly is one of three angular parameters ("anomalies") that define a position~~ along ~~an orbit, the other two being the [[eccentric anomaly]] and the [[mean anomaly]]~~.

	~~==Formulas==~~
	~~===From state vectors===~~
	~~For elliptic orbits '''true anomaly''' <math>\nu\,\!</math>~~ can be ~~calculated~~ from [~~[orbital state vectors]] as~~:

	~~:<math> \nu = \arccos { {\mathbf{e} \cdot \mathbf{r}} \over { \mathbf{\left \|e \right \|} \mathbf{\left \|r \right \|} }}<~~/~~math> &emsp;&emsp;(if <math>\mathbf{r} \cdot \mathbf{v} < 0<~~/~~math> then replace <math>\nu\ </math> by <math>2\pi-\nu\ </math>)~~

	~~where:~~
	* <math> \mathbf{v}\,</math> is [[orbital velocity vector]] of the orbiting body,
	* <math> \mathbf{e}\,</~~math> is [[eccentricity vector]],~~
	* <math> \mathbf{r}\,</math> is [[orbital position vector]] (segment ''fp'') of the orbiting body.

	====~~Circular orbit====~~
	~~For [[circular orbit~~]~~]s the true anomaly is undefined because circular orbits do not have~~ a ~~uniquely determined periapsis~~. ~~Instead one uses~~ the ~~[[argument~~ of ~~latitude]]~~ <~~math~~>~~u\,\!~~<~~/math>:~~

	~~:<math> u = \arccos { {\mathbf{n} \cdot \mathbf{r}} \over { \mathbf{\left \|n \right \|} \mathbf{\left \|r \right \|} }}</math> &emsp;&emsp;(if <math>\mathbf{n} \cdot \mathbf{v} >0</math~~> then ~~replace <math>u\ </math> by <math>2\pi~~-~~u\ </math>)~~

	~~where:~~
	* <math> \mathbf{n} </math> is vector pointing towards the ~~ascending node (i.e~~. the ~~z-component~~ of ~~<math> \mathbf{n} </math>~~ is ~~zero)~~.
	:

	~~====Circular orbit with zero inclination====~~
	~~For [[circular orbit]]s with zero inclination~~ the ~~argument of latitude is also undefined, because there is no uniquely determined line of nodes~~. ~~One uses the [[true longitude]] instead:~~

	:<~~math~~> ~~l = \arccos { r_x \over { \mathbf{\left \|r \right \|}}}~~<~~/math~~> ~~&emsp;&emsp;(if <math> v_x > 0\ </math> then replace <math>l\ </math> by <math>2\pi~~-~~l\ </math>)~~

	~~where:~~
	* <math>r_x \,~~</math> is x-component of [[orbital position vector]] <math>\mathbf{r}</math>~~,
	* <math>v_x \,~~</math> is x-component~~ of ~~[[orbital velocity vector]] <math>\mathbf{v}</math>~~.

	~~===From the eccentric anomaly===~~
	~~The relation between~~ the ~~true anomaly <math>\~~,~~\nu</math> <!--''ν''-->~~ and ~~the [[eccentric anomaly]] ''E'' is:~~

	~~:<math>\cos{\nu} = {{\cos{E} - e} \over {1 - e \cdot \cos{E}}}</math>~~

	~~or equivalently~~

	~~:<math>\tan{\nu \over 2} = \sqrt{{{1+e} \over {1-e}}} \tan{E \over 2}~~.<~~/math~~>

	~~Therefore~~

	:<~~math~~> ~~\nu = 2 \, \mathop{\mathrm{arg}}\left(\sqrt{1~~-~~e} \~~, ~~\cos\frac{E}{2}~~ , ~~\sqrt{1+e}\sin\frac{E}{2}\right)</math>~~

	~~where <math>\operatorname{arg}(x, y)</math> is~~ the ~~polar argument~~ of the ~~vector~~ <~~math~~>~~\left(x, y\right)~~<~~/math~~> ~~(available in many programming languages as~~ the ~~library function [[atan2\|atan2(y~~, ~~x)]] in [[Fortran]]~~ and ~~[[MATLAB]], or as ArcTan(x, y) in [[Wolfram Mathematica]])~~.

	~~===Radius from true anomaly===~~
	~~The radius (distance from the focus~~ of ~~attraction~~ and the ~~orbiting body) is related to~~ the ~~true anomaly by the formula~~

	:~~<math>r = a\cdot{1 - e^2 \over 1 + e \cdot \cos\nu}\,\!<~~/~~math>~~

	~~where ''a'' is the orbit's [[semi-major axis]] (segment ''cz'')~~.
