NGC 338 is a spiral galaxy in the constellation Pisces. Its velocity with respect to the cosmic microwave background is 4479 ± 22 km/s, which corresponds to a Hubble distance of 215.5 ± 15.1 Mly (66.07 ± 4.64 Mpc).[1] In addition, 22 non-redshift measurements give a distance of 223.56 ± 5.04 Mly (68.545 ± 1.544 Mpc).[2] It was discovered in 1877 by Wilhelm Tempel. It was described by Dreyer as "very faint, very small, irregular figure, brighter middle."[3]
