About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.22h 29m 48.19s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.-20° 49' 25.99"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Aquarius
- DistanceDistanceThe physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.About 690 light-years (213 parsecs)
