Coma Berenices is an ancient asterism in the northern sky, which has been defined as one of the 88 modern constellations. It is in the direction of the fourth galactic quadrant, between Leo and Boötes, and it is visible in both hemispheres. Its name means "Berenice's Hair" in Latin and refers to Queen Berenice II of Egypt, who sacrificed her long hair as a votive offering. It was introduced to Western astronomy during the third century BC by Conon of Samos and was further corroborated as a constellation by Gerardus Mercator and Tycho Brahe. It is the only modern constellation named for a historic person.

IC 4141 is a spiral galaxy in the constellation of Coma Berenices. The galaxy is located 900 million light-years away from Earth. Discovered in 1904 by German astronomer Max Wolf, it measures 255,000 light-years across in diameter. With a radial velocity of 19,000 kilometers per second, it is slowly drifting from the Solar System.
IC 3505 is a barred spiral galaxy located 640 million light-years away from the Solar System in the Coma Berenices constellation. With an apparent size of 0.95 by 0.35 arcmin, IC 3505 has an estimated diameter of 170,000 light-years, making it slightly larger compared to the Milky Way. It is categorized as a LINER galaxy with an active galactic nucleus emitting weak emission-lines.
IC 831 is a type E-S0 elliptical galaxy located 300 million light-years away from the Solar System in the constellation of Coma Berenices. It is estimated to be 60,000 light-years in diameter and was first discovered on 25 February 1892 by Rudolf Spitaler, an Austrian astronomer. It is not known whether it has an active galactic nucleus.
IC 4040 is a type SABc spiral galaxy with a bar in Coma Berenices. It is located 353 million light-years away from the Solar System and has an estimated diameter of 105,000 light-years making it slightly larger than the Milky Way. IC 4040 was discovered on April 12, 1891, by Guillaume Bigourdan and is a member of the Coma Cluster.
IC 4026 is a lenticular galaxy located in Coma Berenices. It is located 315 million light-years away from the Solar System and has an approximate diameter of 70,000 light-years which is less the size of the Milky Way. IC 4026 was discovered on May 11, 1896, by astronomer Hermann Kobold and is a member of the Coma Cluster. It has a surface brightness of 11.99 mag/arcsecs meaning it is a high surface brightness galaxy.
IC 2628 is a type SBa barred spiral galaxy with a ring located in Leo constellation. It is located 600 million light-years from the Solar System and has an approximate diameter of 135,000 light-years. IC 2628 was discovered on March 27, 1906, by Max Wolf and is classified as a ring galaxy due to its peculiar appearance. The galaxy has a surface brightness of magnitude 23.8 and located at right ascension (11:11:37.8) and declination (+12:07:21) respectively.
