NGC 4111 is an active lenticular galaxy with extensive star formation areas of the Hubble type S0 / a in the constellation Hounds in the northern sky . It is an estimated 37 million light years from the Milky Way and about 50,000 light years in diameter . Together with NGC 4109, it forms the optical pair of galaxies Holm 333 . It is part of the Ursa Major Galaxy Cluster and a member of the NGC 4051 group ( LGG 269 ).
Images of the galaxy using the Hubble Space Telescope show an unusual concentric ring of dust perpendicular to the galactic disk , possibly the relic of an absorption from another galaxy.
In the same area of the sky are u. a. the galaxies NGC 4117 , NGC 4118 , NGC 4138 , NGC 4143 .
The object was discovered on January 14, 1788 by the astronomer William Herschel using an 18.7 inch mirror telescope.
