NGC 4118 is a dwarf lenticular galaxy[2] located approximately 63 million light-years away[3] in the constellation Canes Venatici. It was discovered April 20, 1857 by R. J. Mitchell.[4] NGC 4118 is a star forming dwarf galaxy,[5] and is connected to the galaxy NGC 4111, along with the nearby NGC 4117, by disturbed H I from NGC 4111.[6]

NGC 4111 is a companion of the galaxy NGC 4117,[7][8] with both galaxies being members of the NGC 4111 Group[9][10] which is part of the Ursa Major Cloud.[11]
