Messier 100 is a grand design intermediate spiral galaxy in the southern part of the mildly northern Coma Berenices. It is one of the brightest and largest galaxies in the Virgo Cluster and is approximately 55 million light-years from our galaxy, its diameter being 107,000 light years, and being about 60% as large. It was discovered by Pierre Méchain in 1781 and 29 days later seen again and entered by Charles Messier in his catalogue "of nebulae and star clusters". It was one of the first spiral galaxies to be discovered, and was listed as one of fourteen spiral nebulae by Lord William Parsons of Rosse in 1850. NGC 4323 and NGC 4328 are satellite galaxies of M100; the former is connected with it by a bridge of luminous matter.
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.

It is around 80,000 light-years in diameter and was discovered on March 23, 1903, by German astronomer Max Wolf. It is unknown whether IC 3403 has an active galactic nucleus.
IC 3053 is a type Sab barred spiral galaxy with a ring located in the Coma Berenices constellation. The galaxy lies 720 million light-years from the Solar System and has an estimated diameter of 180,000 light-years meaning the galaxy is much larger compared to the Milky Way. IC 3053 was first discovered by Royal Harwood Frost on May 7, 1904. Despite listed in the Virgo Cluster Catalogue as VCC 95, it is not a member of the Virgo Cluster due to its high redshift and instead a background galaxy.

The galaxy lies 1.15 billion light-years away from the Solar System and has an estimated diameter of 240,000 light-years meaning it is bigger compared to the Milky Way. IC 3031 was discovered by astronomer Royal Harwood Frost on May 7, 1904.
IC 3482 is a type Sb spiral galaxy in the Coma Berenices constellation. It is located 850 million light-years away from the Solar System. IC 3482 has an apparent size of 0.4 x 0.15 arcmin, meaning it has estimated diameter of 140,000 light-years. IC 3482 was discovered on March 23, 1903, by German astronomer pioneer, Max Wolf. It is located at right ascension of (12:33:01.00) and declination of (27:49:49:10), and has a surface brightness of magnitude 23.
IC 3789, occasionally known as PGC 1619535, is a type Sbc barred spiral galaxy in the Coma Berenices constellation. It is located 872 million light-years away from the Solar System and has an approximate diameter of 150,000 light-years making it slightly larger than the Milky Way.
