About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.12h 7m 33.46s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.39° 32' 53.99"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Centaurus
- 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.170 light-years (52.4 parsecs)

This image was originally black and white and recorded only overall brightness from the F160W (H) filter. These brightness values were translated into a range of reddish hues. Such color "maps" can be useful in helping to distinguish subtly varying brightness in an image.
