NGC 4774, also known as the Kidney Bean Galaxy,[2] is a ring galaxy in the constellation of Canes Venatici. Its velocity with respect to the cosmic microwave background is 8581 ± 24 km/s, which corresponds to a Hubble distance of 126.56 ± 8.87 Mpc (∼413 million light-years).[1] It was discovered by German-British astronomer William Herschel on 17 March 1787.[2]
