The Variation is the second-largest solar perturbation of the Moon's orbit after the Evection, and the third-largest inequality in the motion of the Moon altogether; ( the first and largest of the lunar inequalities is the equation of the centre, a result of the eccentricity & ndash; which is not an effect of solar perturbation ).
