Galaxy NGC 1090 is a Barred Spiral 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). Even though it appears close to another galaxy (NGC 1087), Blackman (1980) found that NGC 1090 is not interacting and should be considered isolated. It lies near the small M-77 (NGC 1068) galaxy group that also includes NGC 1055, NGC 1073, and five small irregular galaxies. However, because of its distance, NGC 1090 probably is not an actual group member, nor does it appear related to galaxy NGC 1094, which lies in the same area of the sky.
Based on the published red shift, (Hubble Constant of 62 Km/sec per Mpc) a rough distance estimate for NGC 1090 is 145 million light years, with a diameter of about 169,000 light years.
Dreyer's description from the New General Catalog(NGC): Very faint, pretty large, irregularly round, brighter middle.
