NGC 4262 is a lenticular galaxy located in the constellation of Coma Berenices.

Characteristics

NGC 4262 is a small and compact barred lenticular galaxy with a high surface brightness central bar.[2] It is a member of the Virgo Cluster at a distance from the Milky Way of around 50 million light-years.[3]

It features an anomalous abundance of neutral hydrogen for a lenticular galaxy, most of it being located on a ring tilted with respect to NGC 4262's galactic plane.[4] Studies with help of the GALEX telescope have found within that ring several clusters of young stars that can be seen on ultraviolet images.[5]

The aforementioned ring is believed to have its origin in NGC 4262 stripping some gas of another galaxy in a close passage, likely its neighbor the spiral Messier 99.[6]
