IC 923 is a lenticular galaxy located in Ursa Major. Its redshift is 0.069243[1] which means the galaxy is 954 million light-years from Earth.[2] IC 923 has apparent dimensions of 0.50 x 0.2 arcmin, meaning it is approximately 139,000 light-years across.[3] IC 923 was discovered in June 1892, by Edward Emerson Barnard[4][5] and is a member of galaxy group V1CG 588.[6]
