NGC 337 is a barred spiral galaxy in the constellation Cetus. Its velocity with respect to the cosmic microwave background is 1,331±22 km/s, which corresponds to a Hubble distance of 64.0 ± 4.6 Mly (19.63 ± 1.41 Mpc). Additionally, 20 non-redshift measurements give a similar distance of 63.11 ± 1.81 Mly (19.350 ± 0.556 Mpc). It was discovered on September 10, 1785 by German-British astronomer William Herschel. It was described by John Dreyer as "pretty faint, large, extended, gradually a little brighter middle, 10th magnitude star 21 seconds of time to the east."
Supernovae
Two supernovae have been observed in NGC 337:
- SN 2011dq (type II, mag. 16.3) was discovered by Berto Monard on May 15, 2011.
- SN 2014cx (type II-P, mag. 15.6) was discovered by Kōichi Itagaki on September 2, 2014.
NGC 337 Group
NGC 337 is the largest and brightest galaxy in the NGC 337 Group (also known as LGG 15). The group includes at least three other galaxies: NGC 274, NGC 275, and NGC 298.
