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.
Dictionary of Military and Associated Terms
The angular distance to a body on the celestial sphere measured north or south through 90 degrees from the celestial equator along the hour circle of the body. Comparable to latitude on the terrestrial sphere. See also magnetic declination; magnetic variation.
