NGC 4488
Galaxy in the constellation of Virgo
From Wikipedia, the free encyclopedia
NGC 4488 is a peculiar lenticular galaxy located in the constellation of Virgo.[2] Its velocity with respect to the cosmic microwave background is 1,317±24 km/s, which corresponds to a Hubble distance of 63.3 ± 4.6 Mly (19.42 ± 1.40 Mpc).[1] However, one non-redshift measurement gives a much closer distance of 26.26 Mly (8.050 Mpc).[3] The galaxy was discovered by astronomer William Herschel on December 28, 1785.[4][5] NGC 4488 is a member of the Virgo Cluster.[6][7]

Structure
NGC 4488 has an unusual rectangular-shaped structure similar to the galaxy LEDA 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]
