Scientific paper

A study of the orbital evolution of active and extinct comets in the inner planetary region by Monte Carlo simulations is presented. One thousand fictitious comets were made to perform random walks according to empirically derived distributions of the perturbations of aphelion distance and perihelion distance; these perturbations were computed in the nonplanar, elliptic restricted three-body problem using the Kustaanheimo-Stiefel regularization for a sample of 60,000 comets. A simulation using infinite lifetimes for all orbits shows that for each active Mars-crossing comet there are 50 extinct comets on similar orbits.
