The 20 pages that link to Equatorial coordinate system, each with the reason it gives.

• Right ascensionNarrower topic: Right ascension is one of this system’s two coordinates.

• DeclinationNarrower topic: Declination is one of this system's two coordinates.

• ConstellationRelated: Modern constellation borders follow lines of these coordinates.

• Celestial equatorNarrower topic: Its two coordinates are defined with respect to the celestial equator and equinox.

• Solar declinationNarrower topic: Solar declination is the Sun’s north–south coordinate in this system.

• Axial precessionRelated: As Earth's axis precesses, the celestial equator and coordinate reference points shift.

• Precession of the equinoxesRelated: Its reference equator and equinox shift over time, so coordinates require an epoch.

• Sidereal timeRelated: Sidereal time supplies the local rotation coordinate needed to use right ascension observationally.

• Circumpolar starRelated: Declination in this system helps classify stars as circumpolar for a given latitude.

• Ecliptic coordinate systemCompared with: Its equator-based coordinates differ from this system's ecliptic-based coordinates.

• Hour angleNarrower topic: Hour angle uses the same equatorial geometry but takes the local meridian as its origin.

• Galactic coordinate systemCompared with: Its equator-based axes differ from the Milky Way-based axes.

• September equinoxRelated: The equinox supplies the reference direction from which right ascension is measured.

• Horizontal coordinate systemCompared with: Its coordinates are tied to the celestial sphere rather than the observer’s horizon.

• Astronomical coordinate systemsBroader topic: It gives sky positions in axes tied to Earth's equatorial plane rather than a local horizon.

• NASA/IPAC Extragalactic DatabaseBroader topic: Right ascension and declination are common position fields in NED records.

• Piscis AustrinusRelated: Its coordinates specify the location of Piscis Austrinus and its stars.

• Canis MinorRelated: Its coordinates specify Canis Minor’s position on star charts and observing apps.

• SerpensNarrower topic: Serpens’s position and boundaries are described with these coordinates.

• Leo MinorNarrower topic: Leo Minor’s stars and boundaries are charted in these coordinates.
