NGC 1023, also known as the Perseus Lenticular Galaxy,[1] is a barred lenticular galaxy, a member of the NGC 1023 group of galaxies in the Local Supercluster. Distance measurements vary from 9.3 to 19.7 million parsecs (30 to 64 million light-years).[2] The supermassive black hole at the core has a mass of Script error: No such module "val"..[3] The black hole was discovered by analyzing the dynamics of the galaxy.[4]

NGC 1023 is included in Halton Arp's Atlas of Peculiar Galaxies, under the category "Galaxies with Nearby Fragments" under the number 135.[5]

NGC 1023 has been estimated to have about 490 globular clusters, consistent with similar early-type galaxies.[6] A number of small galaxies have been found around NGC 1023, the collection of which is labelled the "NGC 1023 Group."[7] NGC 1023 has a satellite galaxy named NGC 1023A, which is a Magellanic spiral galaxy; its globular cluster system is much smaller, estimated to be around six individuals.[6]
