NGC 7300 is an intermediate spiral galaxy in the constellation of Aquarius. Its velocity with respect to the cosmic microwave background is 4,566±24 km/s, which corresponds to a Hubble distance of 219.7 ± 15.4 Mly (67.35 ± 4.73 Mpc).[1] However, 15 non-redshift measurements give a closer mean distance of 181.89 ± 10.31 Mly (55.767 ± 3.162 Mpc).[2] It was discovered by British astronomer John Herschel on 26 July 1830.[3]
