129809647057242500_131Equatorial coordinates: a "celestial coordinates". In right ascension and declination of the two coordinates of any day on the celestial sphere. By Equinox celestial Meridian (time) and in the North by the celestial right ascension circle into perspective by the celestial, or arc length of the clip at the equator, known as the celestial right ascension of measuring direction along the celestial movement on Sunday since the vernal equinox point measured in the opposite direction
TERA CD-key, to hours, minutes, andSeconds. Starting from the equator along the distance between celestial Meridian and celestial body angle is called declination of the celestial bodies. Measuring direction from the equator, from 0-90, North of the Celestial Equator. Equatorial coordinates when υ in order to further address the definition of point coordinates in the point when t varies with location and the problem of change over time, and the introduction of the equatorial coordinate system. The equator is taking days to the baseThis ring, selected chunfendian υ is the origin of the coordinate system, also known as the second equatorial coordinate system.
Υ is the right of the equinox. Υ t of arc for the first coordinate of the object x, called the right ascension

wow cd-key, measured counterclockwise direction from 0h~24h (or 0 ° ~360 °). XT in the equatorial coordinate system, with the angular coordinate systemDeclination is recorded as δ, for the second coordinates of celestial bodies. Because the vernal equinox and the movement of celestial bodies Sunday, therefore any objects in the equatorial coordinate system of declination and right ascension α δ, have no observers in different locations or time change of observation. So is widely used in Astrometry.
