Philoctetes for ten years. Helenus, the prophetic son of King Priam of Troy, was forced to reveal, under torture, that one of the conditions of the Greeks' winning the war was that they needed the bow and arrows of Heracles. Upon hearing this, Odysseus and a group of men (usually including Diomedes) rushed back to Lemnos to recover Heracles' weapons. (As Sophocles writes it in his play named "Philoctetes", Odysseus is accompanied by Neoptolemus, Achilles' son, also known as Pyrrhus. Other versions of the myth don't include Neoptolemus.) Surprised to find the archer alive, the Greeks balked on what to do
2260 Neoptolemus observation by Robert Stephens at the Center for Solar System Studies in 2015, and 2016, gave a concurring period of 8.18 and 8.199 hours with a corresponding amplitude of 0.14 and 0.03 magnitude (). According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, "Neoptolemus" measures between 71.65 and 81.28 kilometers in diameter and its surface has an albedo between 0.051 and 0.0650. The "Collaborative Asteroid Lightcurve Link" adopts the results obtained by IRAS, that is, an albedo of 0.0650 and a diameter of
