NGC 1090 is a barred spiral galaxy located in the constellation Cetus.
NGC 1090 has a pseudo inner ring. The disc has a very low surface brightness.
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]
