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]
