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). It was discovered by German astronomer Albert Marth on 30 October 1863.[2]
According to the NASA/IPAC database, NGC 7312 forms a galaxy pair with NGC 7311 (also known as UGC 12080). The Hubble distance to NGC 7311 is 61.33 ± 4.31 Mpc (∼200 million al), which means that it is much closer than NGC 7312, and therefore the pairing is purely optical.
Two supernovae have been observed in NGC 7312: PSNJ22343424+0548478 (type II, mag 16.6, discovered 17 September 2015)[3] and SN 2024ixe (type IIb, mag. 19.7).[4]
