1869 Philoctetes is a Jupiter trojan asteroid that orbits in the L4 Lagrangian point of the Sun-Jupiter system, in the "Greek Camp" of Trojan asteroids. It was named after the Greek hero Philoctetes, who fought during the Trojan War. It was discovered by Cornelis Johannes van Houten, Ingrid van Houten-Groeneveld and Tom Gehrels on September 24, 1960 in Palomar, California at the Palomar Observatory. 1868 Thersites was also discovered the same day by the same group.
