40092 Memel           Discovered 1998 June 28 by E. W. Elst at the European Southern Observatory.
The Memel River, whose Couronian-Latvian name means silent, dates back to the most recent glacial period. Rising near the city of Minsk, it is a major navigable river of Eastern Europe, flowing through Lithuania before empting into the Baltic Sea.
