5160 Camoes, provisional designation 1979 YO, is an asteroid from the inner regions of the asteroid belt, roughly 9 kilometers in diameter. It was discovered by Belgian astronomer Henri Debehogne and Brazilian astronomer Edgar Netto at ESO's La Silla Observatory in northern Chile, on 23 December 1979.[4]
The asteroid has a well-observed orbit with the lowest possible uncertainty – i.e. a condition code of 0 – and an observation arc that spans over a period of almost 40 years. It orbits the Sun at a distance of 2.2–2.6 AU once every 3 years and 9 months (1,360 days). Its orbit shows a low eccentricity of 0.07 and an inclination of 8 degrees from the plane of the ecliptic. As of 2016, the asteroid's effective size, its composition and albedo, as well as its rotation period and shape remain unknown.[1]
Based on an absolute magnitude of 13.3, the asteroid is calculated to measure 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 Luís de Camões (1524–1580), the greatest of the Portuguese poets, whose epic Os Lusíadas (The Lusiads) displays an extraordinary knowledge of astronomy.[2]
