NGC 320 is a spiral galaxy in the constellation Cetus. Its velocity with respect to the cosmic microwave background is 5,218±36 km/s, which corresponds to a Hubble distance of 251.0 ± 17.7 Mly (76.97 ± 5.43 Mpc).[1] It was discovered by American astronomer Francis Leavenworth in 1886.[2]
NGC 7154 is a Seyfert I galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.[3][4]
Supernova
[edit]One supernova has been observed in NGC 320: SN 2026nwg (Type II, mag. 17.359) was discovered by ATLAS on 27 May 2026.[5]
