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). It was discovered by American astronomer Francis Leavenworth in 1886.
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.
