NGC 664 is aspiral galaxy in theconstellation ofPisces. Its velocity with respect to thecosmic microwave background is 5137 ± 21 km/s, which corresponds to aHubble distance of 247.1 ± 17.3 Mly (75.77 ± 5.31 Mpc).[1] In addition, sixnon redshift measurements give a closer distance of 218.91 ± 3.66 Mly (67.117 ± 1.123 Mpc).[2] It was discovered by British astronomerJohn Herschel on 24 September 1830.[3]
