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

Orbit and classification

Cuyo orbits the Sun at a distance of 1.1–3.2 AU once every 3 years and 2 months (1,151 days; semi-major axis of 2.15 AU). Its orbit has an eccentricity of 0.51 and an inclination of 24° with respect to the ecliptic.

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. The official was published by the Minor Planet Center on 1 June 1975 (M.P.C. 3828).

Physical characteristics

SMASS classification Cuyo is a stony Sl-type. 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. 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.
