11055 Honduras           Discovered 1991 Apr. 8 by E. W. Elst at the European Southern Observatory.
Honduras, in the northern part of the Central American isthmus, is a country of rugged mountains and steep river gorges and dense forest, lined on the Caribbean coast by tropical jungle famed in past centuries for pirates. As in Guatemala there are relics of the Mayan civilisation.
