Galaxy NGC 1090 is a barred spiral galaxy with 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.
Based on the published red shift, (Hubble Constant of ~70 km/s per Mpc) a rough distance estimate for NGC 1090 is 39 +2−1 Mly, with a diameter of ~45 kly.
