5160 Camoes, provisional designation1979 YO, is anasteroid from the inner regions of theasteroid belt, approximately 6 kilometers in diameter. The asteroid was discovered on 23 December 1979, by Belgian astronomerHenri Debehogne and Brazilian astronomerEdgar Netto atESO'sLa Silla Observatory in northern Chile.[5] It was later named for Portuguese poetLuís de Camões.[2]
Camoes orbits the Sun in theinner main-belt at a distance of 2.2–2.6 AU once every 3 years and 9 months (1,359 days). Its orbit has aneccentricity of 0.07 and aninclination of 8° with respect to theecliptic.[1] The asteroid'sobservation arc starts in 1979, as noprecoveries were taken and no identifications were made prior to its discovery.[5]
Based on an absolutemagnitude of 13.3 and assuming a genericalbedo 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'sWide-field Infrared Survey Explorer with its subsequentNEOWISE 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.
Thisminor planet was named after Portugal's and the Portuguese language's greatest poet,Luís de Camões (1524–1580). His epicOs 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 theMinor Planet Center on 6 February 1993 (M.P.C. 21610).[6]
