NGC 337
Galaxy in the constellation Cetus
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."
