Coma Berenices contains the northern portion of the [[Virgo Cluster]] (also known as the Coma–Virgo Cluster), about 60 million light-years away. The portion includes six Messier galaxies. [[Messier 85|M85]] (NGC 4382), considered [[elliptical galaxy|elliptical]] or [[lenticular galaxy|lenticular]], is one of the cluster's brighter members at magnitude nine. M85 is interacting with the spiral galaxy [[NGC 4394]] and the elliptical galaxy [[MCG-3-32-38]].<ref name="Nagle">{{cite web | url =http://www.brastro.org/newsletter/2016-June_Newsletter.pdf |title=Coma Berenices|work=Newsletter of the Baton Rouge Astronomical Society| first=John |last= Nagle|date=June 2016| access-date =15 Aug 2016}}</ref> However, it is relatively isolated from the rest of the cluster.<ref name=Escudero>{{cite journal|doi=10.1093/mnras/stac021|bibcode=2022MNRAS.511..393E|arxiv=2201.01759|title=The complex globular cluster system of the S0 galaxy NGC 4382 in the outskirts of the Virgo Cluster|year=2022|last1=Escudero|first1=Carlos G.|last2=Cortesi|first2=Arianna|last3=Faifer|first3=Favio R.|last4=Sesto|first4=Leandro A.|last5=Smith Castelli|first5=Analía V.|last6=Johnston|first6=Evelyn J.|last7=Reynaldi|first7=Victoria|last8=Chies-Santos|first8=Ana L.|last9=Salinas|first9=Ricardo|last10=Menéndez-Delmestre|first10=Karín|last11=Gonçalves|first11=Thiago S.|last12=Grossi|first12=Marco|last13=Mendes De Oliveira|first13=Claudia|journal=Monthly Notices of the Royal Astronomical Society|volume=511|issue=1 |pages=393–412|doi-access=free }}</ref> [[Messier 88|M88]] (NGC 4501) is a multi-arm spiral galaxy seen at about 30° from edge-on.
