The 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 plate]]s to Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld at Leiden Observatory. The trio are credited with several thousand asteroid discoveries.

It was named after the Greek mythological figure [[Philoctetes]], archer and armor-bearer of Hercules, wounded and left to die on the way to the Trojan War. Since it had been prophesied that Troy could not be taken without the arrows of Hercules, Philoctetes was later taken to Troy, where he killed Paris.<ref name="springer" />

1869 Philoctetes, also designated 4596 P–L, 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 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.[3] 1868 Thersites was also discovered the same day by the same group. The asteroid orbits the Sun at a distance of 4.9–5.6 AU once every 12 years (4,373 days). Its rotation period, size and geometric albedo are unknown.

The 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.

It was named after the Greek mythological figure Philoctetes, archer and armor-bearer of Hercules, wounded and left to die on the way to the Trojan War. Since it had been prophesied that Troy could not be taken without the arrows of Hercules, Philoctetes was later taken to Troy, where he killed Paris.[2]
