NGC 958 is a barred spiral galaxy in the constellation of Cetus. Its velocity with respect to the cosmic microwave background is 5505 ± 17 km/s, which corresponds to a Hubble distance of 81.20 ± 5.69 Mpc (~265 million light-years). However, 19 non-redshift measurements give a closer distance of 58.93 ± 12.91 Mpc (~192 million light-years). The galaxy was discovered by German-British astronomer William Herschel on 20 September 1784.
NGC 958 is a Seyfert II Galaxy, i.e. it has a quasar-like nuclei with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable. The NASA/IPAC Extragalactic Database (NED) lists NGC 958 as a luminous infrared galaxy (LIRG).
Supernovae Three supernovae have been observed in NGC 958: SN 2005A (Type Ia, mag. 17.1) was discovered by the Lick Observatory Supernova Search (LOSS) on 5 January 2005. SN 2022ao (Type Ic, mag. 17.997) was discovered by ATLAS on 5 January 2022. SN 2022acbu (Type II, mag. 20.34) was discovered by the Zwicky Transient Facility on 30 November 2022.
