About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.18h 52m 17.55s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.00° 59' 44.28"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Aquila
- 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.Between 3,300 - 9,800 light-years (1 - 3 kpc) away
