WebDefinition. Define T as the time required for a particular body to complete one orbit. In time T, the radius vector sweeps out 2 π radians, or 360°. The average rate of sweep, n, is then = = , which is called the mean angular motion of the body, with dimensions of radians per unit time or degrees per unit time.. Define τ as the time at which the body is at the pericenter. WebThe mean motion is related to the eccentric anomaly by the Kepler equation, one of the earliest transcendental equations of mathematical astronomy: (2) where Δ t is the elapsed time from some initial epoch t0. The true anomaly, f, is the angular motion relative to the focus. We will return to this momentarily.
