2357 Phereclos Шаблон:IPAc-en is a large Jupiter trojan from the Trojan camp, approximately Шаблон:Convert in diameter. It was discovered on 1 January 1981, by American astronomer Edward Bowell at the Anderson Mesa Station near Flagstaff, Arizona, in the United States.[1] The dark and possibly spherical D-type asteroid belongs to the 30 largest Jupiter trojans and has a rotation period of 14.4 hours.[2] It was named after the shipbuilder Phereclos from Greek mythology.[1]
Orbit and classification
Cebriones is a dark Jovian asteroid orbiting in the trailing Trojan camp at Jupiter's Шаблон:L5 Lagrangian point, 60° behind its orbit in a 1:1 resonance (see Trojans in astronomy). This Jupiter trojan is also a non-family asteroid of the Jovian background population.[3][4]
It orbits the Sun at a distance of 5.0–5.4 AU once every 11 years and 11 months (4,344 days; semi-major axis of 5.21 AU). Its orbit has an eccentricity of 0.05 and an inclination of 3° with respect to the ecliptic.[5] The asteroid was first observed as Шаблон:Mp at Lowell Observatory in September 1929. The body's observation arc begins at Lowell one month later with a precovery taken in October 1929, or more than 51 years prior to its official discovery observation at Anderson Mesa.[1]
Physical characteristics
Phereclos is a dark D-type asteroid, according to the Tholen classification, the SDSS-based taxonomy and the survey conducted by Pan-STARRS.[5][2][6][4][7]
Rotation period
In July 2010, a rotational lightcurve of Phereclos was obtained from photometric observations by Stefano Mottola using the 1.2-meter telescope at Calar Alto Observatory in Spain. Lightcurve analysis gave a rotation period of 14.394 hours with a low brightness variation of 0.09 magnitude (Шаблон:Small), indicative of a nearly spherical shape.[2][8]
Between 2010 and 2017, photometric follow-up observations by Robert Stephens at the Center for Solar System Studies, California, gave several, concurring periods of 7.16 (half-period), 14.345 and 14.49 hours.[2][9][10]Шаблон:EfnШаблон:Efn
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, Phereclos measures between 94.62 and 98.45 kilometers in diameter and its surface has an albedo between 0.049 and 0.0521.[11][12][13]
The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0521 and a diameter of 94.90 kilometers based on an absolute magnitude of 8.94.[2]

Naming
This minor planet was named from Greek mythology after the skilled craftsman and shipbuilder Phereclos (Phereclus; Phereklos), who constructed the ship that Paris used to kidnap Helen. During the Trojan War, he was killed by the Greek hero Meriones.[1] The official naming citation was published by the Minor Planet Center on 1 August 1981 (Шаблон:Small).[14]
