NGC 7364 is a spiral galaxy in the constellation of Aquarius. Its velocity with respect to the cosmic microwave background is 4,480±26 km/s, which corresponds to a Hubble distance of 215.5 ± 15.1 Mly (66.07 ± 4.64 Mpc).[1] Additionally, six non-redshift measurements give a farther mean distance of 230.27 ± 29.46 Mly (70.600 ± 9.034 Mpc).[2] It was discovered by German-British astronomer William Herschel on 1 October 1785.[3][4]
NGC 7364 is a is a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure.[5]
