About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.23h 20m 48.3s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.61° 12' 6.12"
- 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.7,100 light-years (2,100 parsecs)

The Hubble image (right) is a composite of separate exposures acquired by the WFC3/UVIS instrument. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F502N ([O III]) Green: F656N (H-alpha) Red: F658N ([N II])
