4833 Meges
4833 Meges is a large Jupiter trojan from the Greek camp, approximately in diameter. It was discovered on 8 January 1989, by American astronomer Carolyn Shoemaker at the Palomar Observatory in California. The D-type asteroid belongs to the 40 largest Jupiter trojans and has a rotation period of 14.25 hours. It was named after Meges from Greek mythology. Orbit and classification. "Meges" is a dark Jovian asteroid orbiting in the leading Greek camp at Jupiter's Lagrangian point, 60° ahead of its orbit in a 1:1 resonance "(see Trojans in astronomy)". It is also a non -family asteroid in the Jovian background population. It orbits the Sun at a distance of 4.8–5.7 AU once every 12.01 years (4,387 days; semi-major axis of 5.24 AU). Its orbit has an eccentricity of 0.09 and an inclination of 35° with respect to the ecliptic. The asteroid was first observed as "" at Crimea–Nauchnij in December 1975. The body's observation arc begins with its official discovery observation at Palomar in January 1989. Physical characteristics. In both the Tholen- and SMASS-like taxonomy of the Small Solar System Objects Spectroscopic Survey (S3OS2), "Meges" is a dark D-type  asteroid, the most common spectral type in the Jovian asteroid population, especially in the Greek camp. Its V–I color index of 0.94 is typical for most Jupiter trojans. It is also an assumed C-type asteroid. Diameter and albedo. 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, "Meges" measures between 80.16 and 89.39 kilometers in diameter and its surface has an albedo between 0.053 and 0.076. The "Collaborative Asteroid Lightcurve Link" derives an albedo of 0.0635 and a diameter  of 87.52 kilometers based on an absolute magnitude of 8.9. Rotation period. In August 1995, a rotational lightcurve of "Meges" was obtained by ESO astronomers Stefano Mottola and Hans-Josef Schober using the Bochum 0.61-metre Telescope at La Silla Observatory in Chile. Lightcurve analysis gave a well-defined rotation period of 14.250 hours with a brightness variation of 0.13 magnitude (). Photometric observation of this asteroid by Robert Stephens and Daniel Coley at the Center for Solar System Studies during 2016 and 2017, gave two lightcurves with a concurring period of 14.266 and 14.285 hours and an amplitude of 0.27  and 0.44, respectively (). Naming. This minor planet was named by the discoverer from Greek mythology after Meges, commander of the Greek contingent from Dulichium and Echinae who brought 40 ships to the Trojan War. Together with Thoas, after whom 4834 Thoas was named, he helped to persuaded Achilles to rejoin the Trojan War. Meges was one of the men to enter the wooden Trojan Horse. The official naming citation was published by the Minor Planet Center on 25 August 1991 ().
