t to make one revolution. The mean anomaly being known, we may pass to the true anomalyby means of a table of the equation of center (page 174), in whichthe value of the latter is given for each degree or ten degrees ofthe planets mean anomaly. The computation of these tables lies far beyond our… … Fig. 77 THE MOTIONS OP THE PLANETS 149 ellipse of small eccentricity, a planet describes very nearly equalangles about the other focus.
