NGC 4611 is a intermediate spiral galaxy in the constellation of Coma Berenices. Its velocity with respect to the cosmic microwave background is 6,437 ± 22 km/s, which corresponds to a Hubble distance of 94.9 ± 6.7 Mpc (∼310 million light-years).[1] It was discovered by French astronomer Édouard Stephan on 17 May 1881. This galaxy was also observed by the American astronomer Lewis Swift on 20 April 1889, and listed in the Index Catalogue as IC 805.[2]
