About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.05h 38m 42.36s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.-69° 6' 3.24"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Dorado
- 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.170,000 light-years (52,000 parsecs)

The images are composites of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Five filters were used to sample broad and narrow wavelength ranges for the UVIS image. The colors result from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: WFC3/UVIS image of 30 Dor Blue: F336W (U) + F438W (B) Green: F555W (V) Red: F814W (I) Orange/red: F656N (H-alpha)
