NGC 1090 has a pseudo inner ring. The disc has a very low surface brightness. This galaxy has been the site of two known supernovae (in 1962 and 1971). NGC 1090 is not part of a galaxy group, even though it appears close to NGC 1087, M-77 (NGC 1068), NGC 1055, NGC 1073, and five other small irregular galaxies. The distance to NGC 1090 is approximately 124 million light years and its diameter is about 144,000 light years.[2] References1. ^1 2 3 4 5 6 7 {{cite web | title=NASA/IPAC Extragalactic Database | work=Results for NGC 1090 | url=http://nedwww.ipac.caltech.edu/ | accessdate=2006-11-25 }} 2. ^1 {{cite book|last1=Bratton|first1=Mark|title=The Complete Guide to the Herschel Objects|date=2011|publisher=Cambridge University Press|isbn=978-0-521-76892-4|page=166}} External links
