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]
