Its right ascension is between 4 h 37.5 m and 7 h 30.5 m and its declination is between 27.9?and 56.2?in the equatorial coordinate system.
"' Section E : PLANETS "'consist of detailed positional information on each of the major planets including osculating orbital elements, heliocentric ecliptic and geocentric equatorial coordinates, and physical ephemerides.
If you don't much care about accuracy, you can make dramatically simplifying assumptions; the relevant article is Equatorial coordinate system . talk ) 21 : 08, 20 August 2010 ( UTC)
Earth goes through one such complete precessional cycle in a period of approximately 26, 000 years or 1?every 72 years, during which the positions of stars will slowly change in both equatorial coordinates and ecliptic longitude.
The celestial poles are also the poles of the celestial equatorial coordinate system, meaning they have declinations of + 90 degrees and & minus; 90 degrees ( for the north and south celestial poles, respectively ).

"' Section C : SUN "'covers detailed positional information on the Sun, including the ecliptic and equatorial coordinates, physical ephemerides, geocentric rectangular coordinates, times of transit, and the equation of time.
The list below presents instances during the period 2005-2020 in which two of our solar system's planets are in conjunction according to the equatorial coordinate system ( in which the celestial longitude is termed right ascension ).
The components of proper motion in the equatorial coordinate system ( of a given Hipparcos Index Catalogue ( HIP ), now express proper motion in terms of milliarcseconds per year ( mas / yr ), where 1000 mas equals one arcsecond.
"' Section D : MOON "'contains detailed positional information on the Moon including phases, mean elements of the orbit and rotation, lengths of mean months, ecliptic and equatorial coordinates, librations, and physical ephemerides.
Using a telescope equipped with a properly aligned equatorial mount, the observer may also follow the equatorial coordinate system on a star map to " hop " or " slide " along the lines of right ascension or declination from a well known object to find a target.
