}}7092 Cadmus, provisional designation {{mp|1992 LC}}, is a highly eccentric asteroid and near-Earth object of the Apollo group, approximately 3 kilometers in diameter. It was discovered on 4 June 1992, by American astronomer couple Carolyn and Eugene Shoemaker at Palomar Observatory in California, United States.[4] The asteroid was named after Cadmus from Greek mythology.[2] Orbit and classification Cadmus orbits the Sun in the central main-belt at a distance of 0.8–4.3 AU once every 4.04 years (1,474 days). Its orbit has an eccentricity of 0.70 and an inclination of 18° with respect to the ecliptic.Due to a precovery obtained at the Australian Siding Spring Observatory, the body's observation arc already begins in 1980.[4] It has an Earth minimum orbit intersection distance of {{convert |0.0972 |AU |km |abbr=on |sigfig=3}}, which corresponds to 37.9 lunar distances. Physical characteristics As of 2016, the asteroid's effective size, its composition and albedo, as well as its rotation period and shape remain unknown. Naming This minor planet is named for Cadmus, the Phoenician prince, first king of Theben, and one of the greatest heroes before the days of Heracles. The minor planets 1873 Agenor, 52 Europa, 5731 Zeus, 881 Athene, 40 Harmonia and 1388 Aphrodite are named after related figures from Greek mythology.[2] References 1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (7092) Cadmus |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 575 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_6276 |chapter = (7092) Cadmus }}
