NGC 2959 is an intermediate spiral galaxy in the constellation Ursa Major. Its velocity relative to the cosmic microwave background is 4,525 ± 6 km/s, which corresponds to a Hubble distance of 66.7 ± 4.7 Mpc (~218 million light years.). NGC 2959 was discovered by British astronomer John Herschel on 28 October 1831.
NGC 2959 has a luminosity class of I-II and a broad H I line.
According to the Simbad database, NGC 2959 is a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.[2]
Two supernovae have been observed in NGC 2959: SN 2021bbm (type II, mag. 17.4),[3] and SN 2023vog (type II, mag. 18.5).[4]
