    1917 Cuyo, provisional designation 1968 AA, is an stony asteroid and near-Earth object of the Amor group, approximately 5.7 kilometers in diameter. It was discovered on 1 January 1968, by astronomer Carlos Cesco and A. G. Samuel at El Leoncito Observatory, Argentina.[1]

    Orbit and characteristics

    SMASS classification Cuyo is a stony Sl-type.[1]

    In 1989, Cuyo was detected with radar from the Arecibo Observatory at a distance of 0.17 AU. The measured radar cross-section was 2.5 km2.[4]

    According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Cuyo measures 5.7 kilometers in diameter and its surface has an albedo of 0.195.[1]

    Naming

    This minor planet 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]
