(11055) Honduras is an asteroid of the main inner belt that was discovered on April 8, 1991 by the Belgian astronomer Eric Walter Elst at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809). An unconfirmed sighting of the asteroid had already occurred on May 3, 1976 with the provisional designation 1976 JY 2 at the Crimean Observatory in Nautschnyj .
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel in (11055) Honduras assumed a dark surface, so it could, roughly speaking, be trade a C asteroid .
(11055) Honduras was named after the Central American state of Honduras on May 9, 2001 .
