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]

Boxy/Peanut bulge

NGC 4586 has a boxy or peanut-shaped bulge. The bulge has been interpreted to be a bar viewed edge-on. [9] [10]
