Trojan asteroids

Trojan asteroids

Fig. 12.1 . Asteroids that share Jupiterís orbit are known as the Trojan asteroids. They are located near the point where the gravitational force of Jupiter and the Sun are equal. The gravitational perturbations of the inner planets produce slight swinging motions, so the Trojan asteroids oscillate within the two shaded regions. Some of the Trojan asteroids may occasionally move close enough to be captured by Jupiterís gravity, thereby accounting for the planetís unusual outer satellites.
