Plots a) and b) show the radial position of the particle as a function of angular position $\theta$ (degrees) and time ( $\times 10^5$ years), respectively. Plot c) shows the variation of $\theta$ as a function of time ( $\times 10^5$ years). The particle starts in a horseshoe orbit and after about $3.3 \times 10^{5}$ yr shows a highly chaotic behaviour.

Plots a) and b) show the radial position of the particle as a function of angular position $\theta$ (degrees) and time (years), respectively. Plot c) shows the variation of $\theta$ as a function of time. The particle's motion is highly chaotic, changing its radial and angular oscillation amplitudes randomly.

Plots a) and b) show the radial position of the particle as a function of angular position $\theta$ (degrees) and time (years), respectively. Plot c) shows the variation of $\theta$ as a function of time. The particle starts in a horseshoe orbit and apparently keeps its symmetrical path as proposed by Dermott et al. (1979) (see Fig. 1).

Plots a) and b) show the radial position of the particle as a function of angular position $\theta$ (degrees) and time ( $\times 10^5$ years), respectively. Plot c) shows the variation of $\theta$ as a function of time ( $\times 10^5$ years). The particle starts with the same initial conditions as those in Fig. 2, and after about 12 yr it collides with the satellite.
