Some pottery shows Achilles, already having killed Troilus, using his victim's severed head
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
