(11926) Orinoco Main-belt Asteroid
Discovered on 18 December 1992 by E. W. Elst at Caussols.
The Orinoco, a river in the extreme northern part of South America, has its source in the Parima mountain range on the Venezuelan-Brazilian border. Draining 880 000 km2 of the Colombian and Venezuelan region, it forms an enormous delta before reaching the Atlantic Ocean near the island of Trinidad.Naming citation (WGSBN Bull. 3, #13, 10), IAU / Minor Planet Center, via NASA/JPL
