IC 5152 is anirregular galaxy 5.8 millionlight-years fromEarth in theconstellationIndus. It was discovered byDeLisle Stewart in 1908. It is an open question as to whether it is an outlying member of theLocal Group. It is one of the easiest galaxies to resolve into stars, but there is a bright (magnitude 7.7) foreground star (HD 209142) right in front of it that makes deep observations difficult.[4]
