NGC 4571 is a spiral galaxy located in the constellation of Coma Berenices that William Herschel thought it could be the object #91 in Charles Messier' catalog of deep-sky objects,[2] before nearly two centuries later that object was determined to be the nearby barred spiral galaxy NGC 4548.

Physical properties[edit]

The finding of Cepheids by the Canada France Hawaii Telescope in 1994 has allowed to know this galaxy is a member of the Virgo Cluster.[2]

Despite being classified as a late-type galaxy, NGC 4571 has features more typical of spiral galaxies of earlier Hubble type such as a high color index, both low star formation rate and H-Alpha brightness, and relatively little neutral hydrogen,[3] suggesting it may have lost most of its gas due to interactions with Virgo's intragalactic medium and/or past interactions with other galaxies of the cluster.[4][5][5][6]

The low-surface brightness galaxy Malin 1 is located close to this object.[7] It's totally unrelated, however as it lies at a much higher distance.
