1917 Cuyo, provisional designation 1968 AA, is an Amor asteroid, discovered on January 1, 1968, by Carlos Cesco and A. G. Samuel at El Leoncito Observatory, Argentina.[1]
In 1989, this object was detected with radar from the Arecibo Observatory at a distance of 0.17 AU. The measured radar cross-section was 2.5 km2.[3] Based photometric observations and an assumed medium albedo of 0.15, the near-Earth asteroid measures about 5.7 kilometers in diameter.[1]
It is named in honor of the Universidad Nacional de Cuyo, which operated the observatory at El Leoncito in collaboration with Columbia and Yale University. Cuyo is also the name of a region in central-west Argentina.[2]
