NGC 4727 is a largebarred spiral galaxy in theconstellation ofCorvus. Its velocity with respect to thecosmic microwave background for is7,830±23 km/s, which corresponds to aHubble distance of 376.7 ± 26.4 Mly (115.49 ± 8.09 Mpc).[1] It was discovered by German-British astronomerWilliam Herschel on 8 February 1785.[2] It was also observed byLewis Swift on 27 April 1887, causing it to be listed twice in theNew General Catalogue, as NGC 4727 and as NGC 4740.[2]
NGC 4727 andNGC 4724 are listed together asHolm 470 inErik Holmberg'sA Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937.[3]
