NGC 1023 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).^[1] The supermassive black hole at the core has a mass of (4.4±0.5)×10⁷ M_☉.^[2] The black hole was discovered by analyzing the dynamics of the galaxy.^[3]

NGC 1023 is included in Halton Arp's Atlas of Peculiar Galaxies, under the category "Galaxies with Nearby Fragments" under the number 135.^[4]

A number of small galaxies have been found around NGC 1023, the collection of which is labelled the "NGC 1023 group."^[5]
