What is the angular distance of a point north or south of the celestial equator?

The angular distance of a point north or south of the celestial equator is referred to as declination. In celestial navigation and astronomy, declination is measured in degrees, with positive values indicating points north of the celestial equator and negative values indicating points to the south. This measurement plays a similar role in the celestial sphere as latitude does on Earth, providing a way to locate stars and other celestial objects in relation to the celestial equator.

Altitude, on the other hand, describes the angle of an object above or below the observer's horizon and is not specifically related to the celestial equator. Longitude is a geographic coordinate that specifies the east-west position of a point on the Earth's surface and is not applicable to the description provided. Right Ascension is a measure of the angular distance of an object from the vernal equinox along the celestial equator, which is not the same as measuring the distance north or south of the celestial equator. Thus, declination is the term that correctly describes the angular measurement in relation to the celestial equator.
