NGC 1125 is a barred spiral galaxy in the constellation of Eridanus. Its velocity with respect to the cosmic microwave background is 3,087±14 km/s, which corresponds to a Hubble distance of 148.5 ± 10.4 Mly (45.53 ± 3.20 Mpc). It was discovered by German-British astronomer William Herschel on 6 October 1785.

NGC 1125 is a Seyfert II 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. The strongest emission from ionized and molecular gas is seen about 300 parsecs away from the galaxy’s center.
