NGC 4222 is an edge-on spiral galaxy [2] located about 60 million light-years away [3] in the constellation Coma Berenices. [4] It was discovered by astronomer William Herschel on April 8, 1784 and is often misidentified as IC 3087. [5] NGC 4222 is a member of the Virgo Cluster [6] [7] and is a companion of NGC 4216 [8] which lies about 180,000  ly (56  kpc ) away. [9] [8] Despite this, the two galaxies are not interacting. [9]

NGC 4216

NGC 4216 is a metal-rich intermediate spiral galaxy located not far from the center of the Virgo Cluster of galaxies, roughly 55 million light-years away. It is seen nearly edge-on.

NGC 4309

NGC 4309 is a lenticular galaxy located about 55 million light-years away in the constellation Virgo. The galaxy was discovered by astronomer Christian Peters in 1881 and is a member of the Virgo Cluster.

NGC 4323

NGC 4323 is a lenticular or dwarf elliptical galaxy located about 52.5 million light-years away in the constellation Coma Berenices. The galaxy was discovered in 1882 by astronomer Wilhelm Tempel and is a member of the Virgo Cluster.

NGC 4457

NGC 4457 is a spiral galaxy located about 55 million light-years away in the constellation of Virgo. It is also classified as a LINER galaxy, a class of active galaxy defined by their spectral line emissions. NGC 4457 Is inclined by about 33°. It was discovered by astronomer William Herschel on February 23, 1784. Despite being listed in the Virgo Cluster Catalog as VCC 1145, NGC 4457 is a member of the Virgo II Groups which form an extension of the Virgo cluster.

NGC 4606

NGC 4606 is a spiral galaxy located about 55 million light-years away in the constellation of Virgo. NGC 4606 was discovered by astronomer William Herschel on March 15, 1784. It has a disturbed stellar disk suggesting the actions of gravitational interactions. NGC 4607 may be a possible companion of NGC 4606. However, their redshifts differ by about 600 km/s, making it unlikely that they are a gravitationally bound pair. NGC 4606 is a member of the Virgo Cluster.

NGC 4492

NGC 4492 is a spiral galaxy located about 90 million light-years away in the constellation Virgo. NGC 4492 was discovered by astronomer William Herschel on December 28, 1785. It was rediscovered by astronomer Arnold Schwassmann on January 23, 1900 and was listed as IC 3438. NGC 4492 lies in the direction of the Virgo Cluster. However, it is not considered to be a member of that cluster.

NGC 4586

NGC 4586 is a spiral galaxy located about 50 million light-years away in the constellation Virgo. The galaxy was discovered by astronomer William Herschel on February 2, 1786. Although listed in the Virgo Cluster Catalog, NGC 4586 is considered to be a member of the Virgo II Groups which form a southern extension of the Virgo cluster. NGC 4586 is currently in the process of infalling into the Virgo Cluster and is predicted to enter the cluster in about 500 million years.

NGC 4595

NGC 4595 is a spiral galaxy located about 42 million light-years away in the constellation Coma Berenices. NGC 4595 was discovered by astronomer William Herschel on January 14, 1787. NGC 4595 is a member of the Virgo Cluster.

NGC 4596

NGC 4596 is a barred lenticular galaxy located about 55 million light-years away in the constellation Virgo. NGC 4596 was discovered by astronomer William Herschel on March 15, 1784. The unofficial name is Tiffany's Epiphany. NGC 4596 is a member of the Virgo Cluster and has an inclination of about 38°.

NGC 4607

NGC 4607 is an edge-on spiral galaxy located about 56 million light-years away in the constellation Virgo. NGC 4607 was discovered by astronomer R. J. Mitchell on April 24, 1854. The galaxy is a member of the Virgo Cluster.

NGC 4207

NGC 4207 is a spiral galaxy located about 50 million light-years away in the constellation Virgo. The galaxy was discovered by astronomer Heinrich d'Arrest on March 23, 1865. NGC 4207 is a member of the Virgo Cluster.

NGC 4212

NGC 4212 is a flocculent spiral galaxy with LINER activity located about 53 million light-years away in the constellation Coma Berenices. The galaxy was discovered by astronomer William Herschel on April 8, 1784 and was listed in the NGC catalog as NGC 4208. He then observed the same galaxy and listed it as NGC 4212. Astronomer John Louis Emil Dreyer later concluded that NGC 4208 was identical to NGC 4212. NGC 4212 is a member of the Virgo Cluster.

NGC 4237

NGC 4237 is a flocculent spiral galaxy located about 60 million light-years away in the constellation Coma Berenices. The galaxy was discovered by astronomer William Herschel on December 30, 1783 and is a member of the Virgo Cluster. It is also classified as a LINER galaxy and as a Seyfert galaxy.
