Eccentric anomaly

In orbital mechanics, the eccentric anomaly is an angular parameter that defines the position of a body that is moving along an elliptic Kepler orbit. The eccentric anomaly is one of three angular parameters ('anomalies') that define a position along an orbit, the other two being the true anomaly and the mean anomaly.
