Typical dynamical evolution of cometary dust grains to be compared to that of asteroidal dust grains in Fig. 9. The fast evolution induced by PR-drag through the high eccentricity is frequently interrupted by close encounters with the terrestrial planets. Rare short-term resonant trapping with Jupiter is observed at the beginning of the dynamical evolution of dust particles. Smaller grains evolve toward the Sun on a timescale shorter than 10 Myr.
