(10792) Ecuador is a main outer belt asteroid discovered on February 2, 1992 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 November 8, 1990 with the provisional designation 1990 VU at the Australian Siding Spring Observatory near Coonabarabran , New South Wales .
The asteroid belongs to the Eos family , a group of asteroids which typically have large semiaxes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago. According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel in (10792) Ecuador assumed a dark surface, so it could turn out to be if you roughly look parent asteroid classes divided to act as a C asteroid .
(10792) Ecuador was named on May 9, 2001 after the South American country Ecuador .
