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).{{cite web | url = https://ned.ipac.caltech.edu/cgi-bin/nDistance?name=NGC+958 | title = Distance Results for NGC 958 | website = NASA/IPAC EXTRAGALACTIC DATABASE | publisher = NASA | access-date = 10 August 2024}} The galaxy was discovered by German-British astronomer William Herschel on 20 September 1784.{{cite web | url = https://cseligman.com/text/atlas/ngc9a.htm#958 | title = NGC 958 | last = Seligman | first = Courtney | website = Celestial Atlas | access-date = 10 August 2024 }}

The SIMBAD database lists NGC 958 as 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.{{cite simbad | title=NGC 958 | access-date=16 December 2024}} The NASA/IPAC Extragalactic Database (NED) lists NGC 958 as a luminous infrared galaxy (LIRG).
