NGC 7312 is a barred spiral galaxy in the constellation of Pegasus. Its velocity with respect to the cosmic microwave background is 7911 ± 26 km/s, which corresponds to a Hubble distance of 116.68 ± 8.18 Mpc (∼381 million light-years).[1] It was discovered by German astronomer Albert Marth on 30 October 1863.[2]

According to Steven D. Peterson, NGC 7312 forms a galaxy pair with NGC 7311.[3] The Hubble distance to NGC 7311 is 61.33 ± 4.31 Mpc (∼200 million light-years), which is much closer than NGC 7312, and therefore the pairing is purely optical.
