Kepler's equation




One of the important formulae that enables the position of a body in an elliptical orbit to calculated at any given time from its orbital elements. It relates the mean anomaly, M, of the body to its eccentric anomaly, E, by the following:

M = E - e sin E
where e is the eccentricity of the orbit.
