Dziewanna

471143 Dziewanna (provisional designation 2010 EK139) is a trans-Neptunian object in the scattered disc, orbiting the Sun in the outermost region of the Solar System. 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. Based on its absolute magnitude and assumed albedo, it is estimated to have a diameter of approximately 470 kilometers. It was named after Devana (Polish form: Dziewanna), a Slavic goddess of the wilderness, forests and the hunt, in honor of the fact that it was discovered during the Polish OGLE project of Warsaw University, which was led by Udalski. more »
