DETAILS | NGC474 is a ringed spiral which is 'gas poor', meaning that it has probably lost it's gases in an encounter with another galaxy. The peculiar geometry of this galaxy also indicates a three dimensional morphology rather than a disc. NGC470 is also a spiral that may be accreting material from NGC474. The supernova SN 1966H was discovered in this region. [HB89] 0117+031 NED02 and [HB89] 0117+031 NED01 are QSOs |
