The equatorial coordinate system is an astronomical coordinate system in which measurements are based on the celestial equator.
Hence a point on the celestial sphere is located by means of $2$ angular measurements:
- the right ascension $\alpha$, which is the angular distance measured eastwards along the celestial equator from the vernal equinox
- the declination $\delta$, which is the angular distance measured north or south of the terrestrial equator.
