Messier 84 (M84) is an elliptical or lenticular galaxy located in the inner region of the Virgo Cluster, in the constellation Virgo.
The galaxy lies at an approximate distance of 60 million light years from Earth and has an apparent magnitude of 10.1. It has the designation NGC 4374 in the New General Catalogue.
The galaxy is one of the brighter members of the Virgo Cluster, but not easily spotted in 10×50 binoculars. It can be seen with large binoculars and small telescopes, but requires clear, dark skies.
M86, can be seen just 17 arc minutes to the east of M84. The two galaxies appear in the same field of view in binoculars and small telescopes.
In small telescopes, the galaxies appear as small, oval-shaped patches of light with brighter centres. They are best seen in medium-sized and large telescopes. In 8-inch telescopes, several other galaxies can be seen in the vicinity, including NGC 4435, NGC 4388, NGC 4402 and NGC 4438.
