NGC 2466 is an unbarred spiral galaxy in the constellation of Volans. Its velocity with respect to the cosmic microwave background is 5428 ± 10 km/s, which corresponds to a Hubble distance of 261.2 ± 18.3 Mly (80.07 ± 5.61 Mpc).[1] The galaxy was discovered by British astronomer John Herschel on 20 February 1835.[2]
