(11335) Santiago is an asteroid of the main inner belt that was discovered on April 20, 1996 by the Belgian astronomer Eric Walter Elst at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809).
Mean distance from the Sun ( major semiaxis ), eccentricity and inclination of the orbit plane of the asteroid roughly correspond to the Vesta family , a large group of asteroids named after (4) Vesta , the second largest asteroid and third largest celestial body in the main belt. According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic investigation by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (11335) Santiago assumed a dark surface, so it could, roughly speaking, be around trade a C asteroid .
(11335) Santiago was named after Santiago de Chile , the capital of Chile , on March 2, 2000 .
