en.wikipedia.org/wiki/Declination

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. **Declination's** angle is measured north or south of the
**celestial equator**, along the hour circle passing through the point in question.

**Declination** is measured from the **celestial equator**. It extends from 0° at the
**celestial equator** to +90° at the north celestial pole and from 0° at **celestial**
**equator** to -90° at the south celestial pole. While **declination** does not use the
designation N and S, latitude and **declination** are nonetheless closely related
coordinates.

We can locate any object on the celestial sphere by giving it two coordinates,
called the Right Ascension and the **Declination**. These are called celestial
coordinates. Analogous to the longitude on Earth, the Right Ascension of an
object on the celestial sphere is measured along the **celestial equator**, as the
angular distance ...

If you are in the southern hemisphere, the south celestial pole (the SCP) is above
the horizon, the NCP below it. A star on the celestial sphere seems to go around
the observer on a daily path (red circle). The perpendicular angle of a star north
or south of the **celestial equator** is given by its **declination**, indicated by lower ...

**Declination** equals the angle of a star away from the **Celestial Equator** with the
vertex (the common endpoint of the angle) being the center of the earth). A
celestial body on the **Celestial Equator** has a **declination** of 0 and rises due East
and sets due West. (The sun at Vernal and Autumnal Equinox has a **declination**
of 0.).

Jul 20, 2006 **...** Imagine the lines of latitude and longitude ballooning outward from the Earth and
printing themselves on the inside of the sky sphere, as shown at right. They are
now called, respectively, **declination** and right ascension. Directly out from the
Earth's equator, 0° latitude, is the **celestial equator**, 0° **declination**.

Now imagine the Earth's Equator extended out to infinity, the corresponding point
on the celestial sphere is the **celestial equator**. Just as the angle between the
pole and the equator on Earth is a right angle, the same is true of the celestial
sphere. For this reason points on the **celestial equator** are said to have a
**declination** of ...
