IC 1801 is a bar-spiral galaxy of the Hubble type SBb in the constellation Aries north of the ecliptic . It is estimated to be 183 million light years away from the Milky Way and has a diameter of around 85,000 ly. Together with NGC 935 , it forms the interactive galaxy pair Arp 276 . Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This pair of galaxies belongs to the class of interacting double galaxies .
The galaxy belongs to the NGC 932 group with NGC 924 , NGC 930 , and NGC 938 .
The supernova SN 1976H was observed here.
The object was discovered by Stéphane Javelle on December 27, 1897 .
