NGC 7110 is a barred spiral galaxy in the constellation of Piscis Austrinus. Its velocity with respect to the cosmic microwave background is 5044 ± 20 km/s, which corresponds to a Hubble distance of 74.39 ± 5.22 Mpc (∼243 million light-years).[1] It was discovered by British astronomer John Herschel on 23 September 1834.[2]
