11926 Orinoco           Discovered 1992 Dec. 18 by E. W. Elst at Caussols.
The Orinoco, a river in the extreme northern part of South America, has its source in the Parima moutain range on the Venezuelan-Brazilian border. Draining 880~000 km 2 of the Colombian and Venezuelan region, it forms an enormous delta before reaching the Atlantic Ocean near the island of Trinidad.
