The meaning of DECLINATION is angular distance north or south from the celestial equator measured along a great circle passing through the celestial poles. How to use declination in a sentence.

Magnetic declination, sometimes called magnetic variation, is the angle between magnetic north and true north. Declination is positive east of true north and negative when west. Magnetic declination changes over time and with location.

In astronomy, declination (abbreviated dec; symbol δ) is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system, the other being hour angle. The declination angle is measured north (positive) or south (negative) of the celestial equator, along the hour circle passing through the point in question. [1]

The deviation of the compass from true north is an angle called "declination" (or "magnetic declination"). It is a quantity that has been a nuisance to navigators for centuries, especially since it varies with both geographic location and time.

Declination can mean a bending or sloping downward. Things that slope this way, such as the parts of a plant, can be described with the adjective declinate. Declination can also mean …

declination, in astronomy, the angular distance of a body north or south of the celestial equator. Declination and right ascension, an east-west coordinate, together define the position of an object in the sky. North declination is considered positive and south, negative.

Jul 15, 2023 · Declination is expressed in degrees, ranging from +90° (North Celestial Pole) to -90° (South Celestial Pole). For instance, if an object has a declination of +30°, it means it is positioned one-third of the way north of the celestial equator.
