(624) Hector is the largest and brightest asteroid from the group of Trojans on the planet Jupiter .
In astronomy, Trojans are asteroids that move around the sun at L 4 or L 5 Lagrange points on the orbit of the orbiting planet. The asteroid, discovered in 1907, precedes Jupiter at the Lagrange point L 4 .
Hector is an irregularly shaped celestial body in the shape of a dumbbell, 416 km × 131 km × 120 km in size.
The asteroid is orbited by a 12 km large moon named Skamandrios .
It was named after the heroic figure Hector from Greek mythology.
