NGC 4222

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]
