(10454) Vallenar is an asteroid of the inner main belt that was discovered on July 9, 1978 by the German astronomer Hans-Emil Schuster at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809).
The asteroid belongs 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 study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (10558) Karlstad assumed a bright surface, so it could, roughly speaking, be around trade an S asteroid .
The timeless (non- osculating ) orbital elements of (10454) Vallenar are almost identical to those of five smaller asteroids, if one considers the absolute magnitude of 15.6, 15.6, 16.7, 16.8 and 17.1 compared to 14 , 2 starts out: (21291) 1996 VG 6 , (21774) O'Brien , (288314) 2004 BS 36 , (305599) 2008 YB 124 and (337584) 2001 SM 338 .
(10454) Vallenar was named on May 1, 2003 after the Chilean city of Vallenar , the capital of Huasco Province . Vallenar is 90 kilometers north of the La Silla Observatory.
