11875 Rhône           Discovered 1989 Dec. 28 by E. W. Elst at Haute Provence.
The Rhône, a major river in France, has been an important highway for the transportation of merchandise since the time of the Greeks and Romans. Rising in the Swiss Alps, the river flows through Lake Geneva and the cities of Lyon, Valence and Avignon, reaching the Mediterranean Sea at Marseille after 813 km.
