NGC 4559 is an intermediate spiral galaxy with a weak inner ring structure in the constellation Coma Berenices. Its velocity with respect to the cosmic microwave background is 1,096±20 km/s, which corresponds to a Hubble distance of 52.7 ± 3.8 Mly (16.17 ± 1.17 Mpc). However, 26 non-redshift measurements give a much closer distance of 24.56 ± 1.58 Mly (7.530 ± 0.483 Mpc). It was discovered by German-British astronomer William Herschel on 11 April 1785.
