Physical properties
editThe finding ofCepheidsby theCanada France Hawaii Telescopein 1994 has established that this galaxy is a member of theVirgo Cluster.[2]
Despite being classified as alate-type galaxy,NGC 4571 has features more typical of spiral galaxies of earlier Hubble type such as a highcolor index,both lowstar formationrate andH-Alphabrightness, and relatively littleneutral hydrogen,[3]suggesting it may have lost most of its gas due to interactions with Virgo'sintragalactic mediumand/or pastinteractions with other galaxies of the cluster.[4][5][6]
Thelow-surface brightness galaxyMalin 1is located close to this object.[7]It is totally unrelated, however as it lies at a much higher distance.
