471143 Dziewanna           Discovered 2010 Mar. 13 by A. Udalski, S. S. Sheppard, M. Kubiak and C. A. Trujillo at Las Campanas.
Dziewanna is a Slavic Goddess of the wild nature, forests and the hunt. Gold-haired, young and beautiful, she brings the spring and revitalizes the Earth. Wild yellow mullein flowers (Polish: dziewanna) are her symbol. Dried, they served as torches during her celebrations.
