Its velocity with respect to the cosmic microwave background for is 7,830±23 km/s, which corresponds to a Hubble distance of 376.7 ± 26.4 Mly (115.49 ± 8.09 Mpc). It was discovered by German-British astronomer William Herschel on 8 February 1785. It was also observed by Lewis Swift on 27 April 1887, causing it to be listed twice in the New General Catalogue, as NGC 4727 and as NGC 4740.

NGC 4727 and NGC 4724 are listed together as Holm 470 in Erik Holmberg's A Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937.
