IC 2657 is a type E[1] elliptical galaxy located in the constellation Leo. Its redshift is 0.167816,[2] which means IC 2657 is 2.22 billion light-years away.[3] IC 2657 is the second most distant Index Catalogue object after IC 4017[4][5] and the brightest cluster galaxy inside a small galaxy group called WHL J111508.7+134141.[6] A large galaxy, measuring approximately 0.30 x 0.3 arcmin, it spans about 202,000 light-years across[7] and was discovered by Max Wolf on March 27, 1906.[8]
