NGC 4488 is a peculiarlenticular galaxy located in theconstellation ofVirgo.[2] Its velocity with respect to thecosmic microwave background is1,317±24 km/s, which corresponds to aHubble distance of 63.3 ± 4.6 Mly (19.42 ± 1.40 Mpc).[1] However, onenon-redshift measurement gives a much closer distance of 26.26 Mly (8.050 Mpc).[3] The galaxy was discovered by astronomerWilliam Herschel on December 28, 1785.[4][5] NGC 4488 is a member of theVirgo Cluster.[6][7]
NGC 4488 has an unusual rectangular-shaped structure similar to the galaxyLEDA 74886. The galaxy does not have an inner disk. It also has two arms coming off diagonally opposite sides suggesting that NGC 4488 has had a gravitational interaction with another galaxy.[8]
