5160 Camoes, provisional designation 1979 YO, is an asteroid from the inner regions of the asteroid belt, approximately 9 kilometers in diameter. It 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.[4]
The asteroid orbits the Sun at a distance of 2.2–2.6 AU once every 3 years and 9 months (1,360 days). Its well-observed orbit with the lowest possible uncertainty of 0 has a low 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.[4] As of 2016, the asteroid's effective size, its composition and albedo, as well as its rotation period and shape remain unknown.
Based on an absolute magnitude of 13.3, the asteroid measures between 6 and 12 kilometers in diameter, assuming an albedo in the range of 0.05 to 0.25.[3] Since asteroids in the inner main-belt are often of a silicaceous rather than of a carbonaceous composition, with higher albedos, typically around 0.20, the asteroid's diameter might be on the lower end of NASA's published conversion table, as the higher the body's reflectivity (albedo), the smaller its diameter, for a given absolute magnitude (brightness).[3]
The 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] Naming citation was published on 6 February 1993 (M.P.C. 21610).[5]
