  1. Declination

    In astronomy, declination is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system, the other being hour angle. Declination's angle is measured north or south of the celestial equator, along the hour circle passing through the point in question. The root of word the declination means "a bending away" or "a bending down". It comes from the same root as the words incline and recline.
