2674 Pandarus
2674 Pandarus is a large Jupiter trojan from the Trojan camp, approximately in diameter. It was discovered on 27 January 1982, by astronomers at Harvard's Oak Ridge Observatory near Harvard, Massachusetts, in the United States. The likely elongated D-type asteroid has a rotation period of 8.48 hours and belongs to the 50 largest Jupiter trojans. It was named after Pandarus from Greek mythology.
Orbit and classification
Pandarus is a dark Jovian asteroid orbiting in the trailing Trojan camp at Jupiter's Lagrangian point, 60° behind its orbit in a 1:1 resonance '. It is also a non-family asteroid of the Jovian background population.It orbits the Sun at a distance of 4.8–5.5 AU once every 11 years and 9 months. Its orbit has an eccentricity of 0.07 and an inclination of 2° with respect to the ecliptic. The body's observation arc begins with its first observation as ' at Crimea–Nauchnij in April 1972, almost 10 years prior to its official discovery observation at Oak Ridge.
Naming
This minor planet was named after Pandarus from Greek mythology, He was the Lycian warrior whose treacherous wounding of the Greek Spartan leader Menelaus broke the truce in the Trojan War. The verb "to pander" and "pandering" are derived from his name. The official naming citation was published by the Minor Planet Center on 6 June 1982.Physical characteristics
Pandarus has been characterized as a D-type asteroid by the survey conducted by Pan-STARRS. It is also a dark D-type in the Tholen classification and in the SDSS-based taxonomy.Rotation period
In the 1980s, a rotational lightcurve of Pandarus was obtained from photometric observations by Linda French using the SMARTS 0.9-meter reflector at Cerro Tololo Inter-American Observatory in Chile. Lightcurve analysis gave a well-defined rotation period of 8.480 hours with a brightness variation of 0.58 magnitude, indicative of a non-spheroidal shape.In 2015 and 2017, Robert Stephens and Daniel Coley at the Center for Solar System Studies in California, measured two concurring periods of 8.461 and 8.470 hours with an amplitude of 0.49 and 0.65 magnitude, respectively.
