Edge-on spiral galaxy in the constellation Coma Berenices
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]
