5160 Camoes, provisional designation 1979 YO, is an asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. The asteroid was discovered on 23 December 1979, by Belgian astronomer Henri Debehogne and Brazilian astronomer Edgar Netto at ESO's La Silla Observatory in northern Chile.[5] It was later named for Portuguese poet Luís de Camões.[2]

Orbit and classification[]

Camoes orbits the Sun in the inner main-belt at a distance of 2.2–2.6 AU once every 3 years and 9 months (1,359 days). Its orbit has an eccentricity of 0.07 and an inclination of 8° with respect to the ecliptic.[1] The asteroid's observation arc starts in 1979, as no precoveries were taken and no identifications were made prior to its discovery.[5]

Physical characteristics[]

Based on an absolute magnitude of 13.3 and assuming a generic albedo over the range of 0.05 to 0.25, Camoes measures between 6 and 12 kilometers in diameter.[4]

According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Camoes measures 6.0 kilometers in diameter and its surface has an albedo of 0.259.[3] As of 2016, the asteroid's composition, rotation period and shape remain unknown.

Naming[]

This minor planet was named after Portugal's and the Portuguese language's greatest poet, Luís de Camões (1524–1580). His epic Os Lusíadas (The Lusiads), a fantastical interpretation of the Portuguese voyages of discovery during the 15th and 16th centuries, shows an extraordinary knowledge of astronomy.[2] The official naming citation was published by the Minor Planet Center on 6 February 1993 (M.P.C. 21610).[6]
