NGC 4586

NGC 4586 is a spiral galaxy located about 50 million light-years away^[2] in the constellation Virgo.^[3] The galaxy was discovered by astronomer William Herschel on February 2, 1786.^[4] Although listed in the Virgo Cluster Catalog,^[5] NGC 4586 is considered to be a member of the Virgo II Groups which form a southern extension of the Virgo cluster.^[6][7] 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.^[8]
