}}3596 Meriones ({{IPAc-en|m|ə|ˈ|r|aɪ|oʊ-|n|iː|z}} {{Respell|mə|RY|o|neez}}), provisional designation {{mp|1985 VO}}, is a large Jupiter trojan from the Greek camp, approximately {{convert|80|km|mi|abbr=off|sigfig=2|sp=us}} in diameter. It was discovered on 14 November 1985, by Danish astronomers Poul Jensen and Karl Augustesen at the Brorfelde Observatory near Holbæk, Denmark.[1] The assumed C-type asteroid belongs to the 50 largest Jupiter trojans and has a rotation period of 12.96 hours.[5] It was named after the Cretan leader Meriones from Greek mythology.[1]

Orbit and classification

Meriones is a dark Jovian asteroid orbiting in the leading Greek camp at Jupiter's {{L4}} Lagrangian point, 60° ahead of the Gas Giant's orbit in a 1:1 resonance (see Trojans in astronomy). It is also a non-family asteroid in the Jovian background population.[7]

It orbits the Sun at a distance of 4.8–5.5 AU once every 11 years and 9 months (4,293 days; semi-major axis of 5.17 AU). Its orbit has an eccentricity of 0.07 and an inclination of 24° with respect to the ecliptic. The body's observation arc begins with a precovery taken at Uccle Observatory in October 1950, or 35 years prior to its official discovery observation at Brorfelde.[1]

Naming

This minor planet was named from Greek mythology after Meriones, who co-commanded together with the Greek hero Idomeneus the Cretan contingent in the Trojan War, where they slew many Trojans, especially in the Battle of the Ships.[1]

The official naming citation was published by the Minor Planet Center on 7 September 1987 ({{small|M.P.C. 12211}}).[30]

Physical characteristics

Meriones is an assumed, carbonaceous C-type asteroid.[5]

Rotation period

In 1991, a rotational lightcurve of Meriones was published by German and Italian astronomers. Lightcurve analysis of the photometric observations gave a rotation period of 12.96 hours with a brightness amplitude of 0.15 magnitude ({{small|U=2}}).[5][12]

Diameter and albedo

According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Meriones measures 73.28 and 87.38 kilometers in diameter and its surface has an albedo of 0.064 and 0.048, respectively.[10][11] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057, and derives a diameter of 75.09 kilometers based on an absolute magnitude of 9.35.[5]
