From enchantedlearning.com:
Trojan asteroids are asteroids that orbit in gravitationally stable Lagrange points in a planet's orbit, either trailing it or preceding it (these places are where the gravitational attraction of the Sun and of the planet balance each other).
Jupiter has the most Trojan asteroids; Mars also has some. Achilles was the first Trojan asteroid found.
