2. (Astron.) The great circle of the celestial sphere, coincident with the plane of the earth's equator; -- so called because when the sun is in it, the days and nights are of equal length; hence called also the {equinoctial}, and on maps, globes, etc., the {equinoctial line}. [1913 Webster]

{Equator of the sun} or {Equator of a planet} (Astron.), the great circle whose plane passes through through the center of the body, and is perpendicular to its axis of revolution.

{Magnetic equator}. See {Aclinic}. [1913 Webster]
