NGC 1191

NGC 1191 is a lenticular galaxy approximately 406 million light-years away from Earth in the constellation of Eridanus.[1] It was discovered by American astronomer Francis Leavenworth on December 2, 1885 with the 26" refractor at Leander McCormick Observatory.[3]

Together with NGC 1189, NGC 1190, NGC 1192 and NGC 1199 it forms Hickson Compact Group 22 (HCG 22) galaxy group.[4] Although they are considered members of this group, NGC 1191 and NGC 1192 are in fact background objects, since they are much further away compared to the other members of this group.[5]
