16560 Daitor
16560 Daitor (/ˈdeɪtər/ DAY-tər; provisional designation 1991 VZ5) is a large Jupiter trojan from the Trojan camp, approximately 44 kilometers (27 miles) in diameter. It was discovered on 2 November 1991, by Belgian astronomer Eric Elst at the La Silla site of the European Southern Observatory in Chile.[1] The carbonaceous C-type asteroid is one of the largest Jupiter trojans with an unknown rotation period.[10] It was named after the Trojan warrior Daitor from Greek mythology.[1] Orbit and classificationDaitor is a Jovian asteroid in the so-called Trojan camp, located in the L5 Lagrangian point, 60° behind Jupiter, orbiting in a 1:1 resonance with the Gas Giant .[3] It is also a non-family asteroid of the Jovian background population.[4] It orbits the Sun at a distance of 4.9–5.3 AU once every 11 years and 4 months (4,152 days; semi-major axis of 5.06 AU). Its orbit has an eccentricity of 0.04 and an inclination of 15° with respect to the ecliptic.[2] The body's observation arc begins with a precovery published by the Digitized Sky Survey and taken at Palomar Observatory in October 1955, more than 36 years prior to its official discovery observation at La Silla.[1] NamingThis minor planet was named from Greek mythology after the Trojan warrior Daitor (Dai'tor), who was killed by Teucer (Teukros) during the Trojan War.[1][11] The official naming citation was published by the Minor Planet Center on 27 May 2010 (M.P.C. 70409).[12] Physical characteristicsIn the SDSS-based taxonomy, Daitor is a carbonaceous C-type,[8][9] while most Jupiter trojans are D-type asteroids. Rotation periodAs of 2018, no rotational lightcurve of Daitor has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.[10] Diameter and albedoAccording to the survey carried out by the Japanese Akari satellite, the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, and the Infrared Astronomical Satellite IRAS, Daitor measures between 43.38 and 51.42 kilometers in diameter and its surface has an albedo between 0.029 and 0.053.[5][6][7] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 40.33 kilometers based on an absolute magnitude of 10.7.[10]
