Mean Sun Definition

noun
A hypothetical sun thought of as moving uniformly along the celestial equator at a speed equal to the actual sun's average speed along the ecliptic: hypothesized as a basis for keeping time, because the actual sun does not travel along the ecliptic at a uniform rate.
Webster's New World
