328563 Mosplanetarium           Discovered 2009 Sept. 17 by T. V. Kryachko at Zelenchukskaya Stn.
Named for the Moscow planetarium, the oldest in Europe, which celebrated its 85th anniversary in 2014. The planetarium is the largest Russian center of popularization of scientific knowledge, and it has made important contribution to development of astronomy and cosmonautics.
