NGC 3686 is a spiral galaxy in the constellation Leo. It has two spiral arms and a weak bar.[3]
It forms a quartet with three other spiral galaxies, NGCs 3681, 3684, and 3691.[6] It was discovered on 14 March 1784 by William Herschel.[7] It is a member of the NGC 3607 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster.[8]
