Discovered on 26 July 1998 by E. W. Elst at La Silla.
The Marne is a river in France with its source on the Langres plateau. With a length of nearly 525 km it runs generally in a north-northwest direction, passing the cities of Chaumont and Chalôns-sur-Marne. Below the city of Reims it changes its direction to continue its path to Paris, where it enters the Seine river.Naming citation (MPC batch dated 2014-09-09), IAU / Minor Planet Center, via NASA/JPL
