NGC 833

NGC 833 is an intermediate spiral galaxy in the constellation Cetus. It has an active Hubble-type Sa nucleus, and lies south of the celestial equator. It is estimated to be 173 million light-years from the Milky Way and about 75,000 light-years in diameter. Together with NGC 835, NGC 838 and NGC 839 it forms a group of galaxies cataloged as Hickson Compact Group 16 (Arp 318). Halton Arp divided his catalog of unusual galaxies into groups based on purely morphological criteria.
