It was discovered by w:Pierre Méchain in w:1781. It is the northernmost outlier of the w:Virgo cluster discovered as of 2004.
The type I w:supernova, w:1960R was discovered in M85 on Dec 20, w:1960 and reached an w:apparent magnitude of 11.7.
M85 is interacting with the nearby w:spiral galaxy w:NGC 4394, and a small w:elliptical galaxy called w:MCG 3-32-38[3].
