4695 Mediolanum           Discovered 1985 Sept. 7 by H. Debehogne at the European Southern Observatory.
Mediolanum is the Latin name of Milano, city placed in the North of Italy. In 1861 G. V. Schiaparelli discovered (69) Hesperia from the Osservatorio Astronomico di Brera. Name suggested by S. Baroni and S. Foglia.
