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 Luis de Camoes . [2]

Orbit and classification [ edit ]

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 [ edit ]

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 [ edit ]

This minor planet was named after Portugal's and the Portuguese language's greatest poet, Luis de Camoes (1524?1580). His epic Os Lusiadas (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]
