Messier 85 (also known as M85 or NGC 4382 or PGC 40515 or ISD 0135852) is a lenticular galaxy, or elliptical galaxy for other authors,[4]Template:R/superscript in the Coma Berenices constellation. It is 60 million light-years away, and has a diameter of about 36.99 kiloparsecs (120,600 light-years) across.[1][5]

Pierre Méchain discovered M85 in 1781. It is within the outskirts of the Virgo Cluster, and is relatively isolated.[6]Template:R/superscript

Properties

M85 is extremely poor in neutral hydrogen[7]Template:R/superscript and has a very complex outer structure with shells and ripples that are thought to have been caused by a merger with another galaxy that took place between 4 and 7 billion years ago,[7] as well as a relatively young (<3 billion years old) stellar population on its centermost region, some of it in a ring, that may have been created by a late starburst.[8]Template:R/superscript Like other massive, early-type galaxies, it has different populations of globular clusters. Aside from the typical "red" and "blue" populations, there is also a population with intermediate colors and an even redder population.[6] It is likely transitioning from being a lenticular galaxy into an elliptical galaxy.[6]

While indirect methods imply that Messier 85 should contain a central supermassive black hole of around 100 million solar masses,[9]Template:R/superscript velocity dispersion observations imply that the galaxy may entirely lack a central massive black hole.[10]Template:R/superscript

M85 is interacting with the nearby spiral galaxy NGC 4394, and a small elliptical galaxy called MCG 3-32-38.[11]Template:R/superscript

Compared to other early-type galaxies, M85 emits a relatively smaller proportion of X-rays.[6]

Novae and Supernovae

Two supernovae and one luminous red nova have been observed in M85:
