'''Declination''' of an object in the sky is the angular distance to the celestial equator. The unit of declination is degree (<sup>o</sup>). The declination has a positive value for objects north of the equator , negative values for objects south of the equator. The abbreviation of declination is the greek letter δ. Besides the [[right ascension]], the declination is the second coordinate in the [[equatorial coordinate system]].<br />

===examples===<br />
<br />
* an object on the celestial equator has a declination of δ = 0<sup>o</sup><br />
* an object above the north pole has a declination of δ = +90<sup>o</sup><br />
* an object above the south pole has a declination of δ = -90<sup>o</sup><br />
* an object in the [[zenith]] has a declination equal to the [[latitude]] of the observer</div>imported>Thorsten Alteholz
