equatorial coordinate component
subject			fact

equatorial coordinate component	is a component of equatorial coordinate
	is a kind of coordinate component
quantity	has unit
number	has value

Kinds of equatorial coordinate component :

• declination (8 facts) (δ) - Angular distance above (positive) or below (negative) the celestial equator. One of the co-ordinates, with right ascension, that defines the position of a heavenly body., Location on the sky in a north-south direction. Lines of declination are the celestial equivalent of latitude on Earth. Compare right ascension., Astronomical coordinate. Equivalent to latitude. The angle in degrees above or below the Celestial Equator, i.e. the projection onto the sky of the Earth's equator. Range of declination is from from zero to ± 90°., Angular distance on the celestial sphere north or south of the celestial equator. It is measured along the hour circle passing through the celestial object. Declination is usually given in combination with right ascension or hour angle., Angular distance north (+) or south (-) of the celestial equator to some object, measured in degrees, minutes, and seconds of arc along an hour circle passing through the object. Declination is analogous to latitude on the Earth's surface.
• distance (3 facts) - The distance to a celestial object measured from the center of the Earth or Sun, in units of parsec or lightyear
• right ascension (4 facts) (α) - Angular distance on the celestial sphere measured eastward along the celestial equator from the equinox to the hour circle passing through the celestial object. Right ascension is usually given in combination with declination.
