20180 Annakolény           Discovered 1996 Dec. 27 by A. Galád and A. Pravda at Modra.
Anna Kolény took part in the birth of Slovak sovereignty in the nineteenth century. The first session of the Slovak National Council was held in 1848 in her house in Myjava. This house became a cultural site in 1970, with the exposition of Slovak National Council's Museum.
