About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.00h 42m
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.+41° 15'
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Andromeda
- 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.2.5 million light-years (0.8 megaparsecs)

This images is a composite of separate exposures acquired by the ACS and WFC3 instruments on the Hubble Space Telescope. Several filters were used to sample broad wavelength ranges. 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: WFC3/UVIS F336W (U) Green: ACS/WFC F475W (g) Yellow: ACS/WFC F814W (I) Red: WFC3/IR F160W (H)
