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.
Feb 26, 2019 · Declination (green) is measured in degrees north and south of the celestial equator. Right ascension, akin to longitude, is measured east from the equinox. The red circle is the Sun's apparent path around the sky, which defines the ecliptic.
Declination is measured in degrees (°), arc-minutes (') and arc-seconds ("), and is similar to latitude on Earth. There are 60 arc-minutes in a degree and 60 arc-seconds in an arc-minute. Declination measures how far overhead an object will rise in the sky, and is measured as 0° at the equator, +90° at the North Pole and -90° at the South Pole.
Mar 22, 2016 · Declination is measured in degrees (°) minutes (‘) and seconds (“). There are 60 seconds to a minute, and 60 minutes to one degree. The celestial equator is located at 0°, and everything above this is said to be in the north of the celestial sphere and is given a positive value of declination.
The declination (Dec) measures how far an object is above or below the celestial equator. It is an angle, measured in degrees and ranges from -90° to 90°. A negative value means south of the equator.
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.
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.
