:4501 Eurypylos

Eurypylos is a dark Jovian asteroid in a 1:1 orbital resonance with Jupiter. It is located in the leading Greek camp at the Gas Giant's {{L4}} Lagrangian point, 60° ahead of its orbit {{crossreference|(see Trojans in astronomy)}}. It is also a non-family asteroid in the Jovian background population. It orbits the Sun at a distance of 4.9–5.5 AU once every 11 years and 11 months (4,342 days; semi-major axis of 5.21 AU). Its orbit has an eccentricity of 0.05 and an inclination of 8° with respect to the ecliptic. The body's observation arc begins with a precovery taken at Palomar Observatory in December 1951, more than 36 years prior to its official discovery observation at La Silla.

Eurypylos is an assumed C-type, while most larger Jupiter trojans are D-type asteroids.

In March 2013, a rotational lightcurve of Eurypylos was obtained from photometric observations by Robert Stephens at the Center for Solar System Studies in Landers, California. Lightcurve analysis gave a rotation period of {{val|6.054|0.001}} hours with a brightness amplitude of 0.24 magnitude ({{small|U=2+}}).{{efn|name=lightcurve-plots-CS3}}

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Eurypylos measures 45.52 kilometers in diameter and its surface has an albedo of 0.065, while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 46.30 kilometers based on an absolute magnitude of 10.4.

This minor planet was named from Greek mythology after the legendary king Eurypylus, the leader of the Thessalian contingent, who brought 40 ships to the siege of Troy. During the Trojan War, he was wounded by an arrow from Paris but was rescued by Patroclus. The official naming citation was published by the Minor Planet Center on 4 October 1990 ({{small|M.P.C. 17031}}).
