1869 Philoctetes is a Jupiter trojan from the Greek camp, approximately 23 kilometers in diameter.
It was discovered on September 24, 1960, by the Dutch and Dutch–American astronomers Cornelis van Houten , Ingrid van Houten-Groeneveld and Tom Gehrels at Palomar Observatory on Palomar Mountain, California.[4] Philoctetes from Greek mythology.[3] 1868 Thersites .
Orbit and classification [ edit ]
Philoctetes orbits in the L 4 Lagrangian point of the Sun–Jupiter system, in the "Greek Camp" of Trojan asteroids.[5] AU eccentricity of 0.07 and an inclination of 4° with respect to the ecliptic .[1]
Physical characteristics [ edit ]
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Philoctetes measures 22.7 kilometers in diameter, and its surface has an albedo of 0.104.[6]
As of 2017, the body's rotation period and shape remain unknown.[1] [7]
Survey designation [ edit ]
The survey designation P-L stands for Palomar–Leiden , named after Palomar Observatory and Leiden Observatory , which collaborated on the fruitful Palomar–Leiden survey in the 1960s. Gehrels used Palomar's Samuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld at Leiden Observatory. The trio are credited with several thousand asteroid discoveries.[8]
This minor planet was named after the Greek mythological figure Philoctetes , famed archer and participant in the Trojan War , where he killed Paris , son of the Trojan King Priam .[3] naming citation was published by the Minor Planet Center on 1 June 1975 (M.P.C. 3826[9]
