Dziewanna was discovered on 13 March 2010 by astronomers Andrzej Udalski, Scott Sheppard, Marcin Kubiak and Chad Trujillo at the Las Campanas Observatory in Chile.[1] Based on its absolute magnitude and assumed albedo, it is estimated to have a diameter of approximately 470 kilometers.[6] It was named after Devana (Polish form: Dziewanna), a Slavic goddess of the wilderness, forests and the hunt,[1] in honor of the fact that it was discovered during the Polish OGLE project of Warsaw University, which was led by Udalski.[11]
