Шаблон:Short description Шаблон:Infobox planet
3596 Meriones Шаблон:IPAc-en is a large Jupiter trojan from the Greek camp, approximately Шаблон:Convert 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.[2] 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 Шаблон:L4 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.[3]
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.[4] 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 (Шаблон:Small).[5]
Physical characteristics
Meriones is an assumed, carbonaceous C-type asteroid.[2]
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 (Шаблон:Small).[2][6]
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.[7][8] 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.[2]
