M 85
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, in the Coma Berenices constellation. It is 60 million light-years away, and it is estimated to be 125,000 light-years across.
It was discovered by Pierre Méchain in 1781.
While indirect methods imply that Messier 85 should contain a central supermassive black hole of around 100 million solar masses, velocity dispersion observations imply that the galaxy may entirely lack a central massive black hole.
