Asteroids orbital stability according to our criteria of stable (panel a) or unstable (panel b) orbit and the Lyapunov time (panel c). In panel a we represented the asteroid (3200)Phaethon’s perihelion evolution. This asteroid has a stable orbit (T_L = 226 yr). In panel b we represent the asteroid 2002GJ8 perihelion evolution. This asteroid has an unstable orbit (T_L = 63 yr). And in panel c is the representation of T_L for all associated asteroids.
