2363 Cebriones (/sɪˈbraɪ.əniːz/ si-BRY-ə-neez), provisional designation 1977 TJ3, is a large Jupiter trojan from the Trojan camp, approximately 84 kilometers (52 miles) in diameter. It was discovered on 4 October 1977, by astronomers at the Purple Mountain Observatory in Nanking, China.[1] The dark D-type asteroid is one of the 40 largest Jupiter trojans and has a rotation period of 20 hours.[3] It was named after Cebriones, Hektor's charioteer from Greek mythology.[1]
Orbit and classification
Cebriones is a dark Jovian asteroid orbiting in the trailering Trojan camp at Jupiter's L5 Lagrangian point, 60° behind on the Gas Giant's orbit in a 1:1 resonance (see Trojans in astronomy). It is also a non-family asteroid of the Jovian background population.[5][13]
It orbits the Sun at a distance of 5.0–5.4 AU once every 11 years and 11 months (4,338 days; semi-major axis of 5.21 AU). Its orbit has an eccentricity of 0.04 and an inclination of 32° with respect to the ecliptic.[2] The body's observation arc begins with a precovery taken at Palomar Observatory in August 1953, more than 24 years prior to its official discovery observation at Nanking.[1]
Naming
This minor planet was named from Greek mythology after King Priam's illegitimate son, Cebriones (Kebriones). He was the half-brother of Hektor and his final charioteer during the Trojan War, wounded in the duel between Hektor and Patroclus.[1] The official naming citation was published by the Minor Planet Center on 1 August 1981 (M.P.C. 6209).[16]
Physical characteristics
In the Tholen classification, Cebriones is a dark D-type asteroid.[2][3][13]
Rotation period
In February 1992, a rotational lightcurve of Cebriones was obtained from photometric observations by Stefano Mottola and Anders Erikson using the now decommissioned ESO 1-metre telescope at La Silla Observatory in Chile. Lightcurve analysis gave a rotation period of 20.05 hours with a brightness variation of 0.22 magnitude (U=3),[10] superseding a previous measurement of a fragmentary lightcurve that gave 3.8 hours only (U=1).[9]
In May 2008 and September 2010, observations by Brian A. Skiff and Adrián Galád gave a concurring period of 20.081 and 20.5 hours with an amplitude of 0.22 and 0.13, respectively (U=2+3).[11][12]
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, Cebriones measures between 81.84 and 95.98 kilometers in diameter and its surface has an albedo between 0.044 and 0.0599.[6][7][8]
The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0599 and a diameter of 81.84 kilometers based on an absolute magnitude of 9.11.[3]
