653 Berenike

653 Berenike is a main-belt asteroid discovered on 27 November 1907 by Joel Hastings Metcalf at Taunton, Massachusetts.[1] It is named after Berenice II of Egypt, after whom the constellation Coma Berenices is also named. The name may have been inspired by the asteroid's provisional designation 1907 BK.
