patroclus orbits in jupiter's trailing lagrangian point, l5, in an orbit called the 'trojan node' after one of the sides in the legendary trojan war (the other node is called the 'greek node'). patroclus is the only object in the trojan camp to be named after a greek character; the naming rules for the trojan asteroids were not made until after patroclus was named (similarly, the asteroid hektor is the only trojan character to appear in the greek camp).
