Jupiter Trojan - Nomenclature

Nomenclature

The custom of naming all asteroids in Jupiter's L₄ and L₅ points after famous heroes of the Trojan War was suggested by Johann Palisa of Vienna, who was the first to accurately calculate their orbits. Asteroids in the L₄ group are named after Greek heroes (the "Greek node or camp" or "Achilles group"), and those at the L₅ point are named after the heroes of Troy (the "Trojan node or camp"). Confusingly, 617 Patroclus was named before the Greece/Troy rule was devised, and a Greek name thus appears in the Trojan node; the Greek node also has one "misplaced" asteroid, 624 Hektor, named after a Trojan hero.
