- Abstract
Presents the results of a numerical study on encounter frequencies of fictitious Halley-like comets with the planets in a dynamical model of the solar system, which takes into account the gravitational forces of the Sun and the planets Venus through Neptune. The encounter frequencies of the comets' orbits was computed using two different "spheres of influence' and the result compared. In both cases, it turned out that the encounter frequency of the fictitious Halley-like comets with Jupiter and Saturn is about a factor 10 to 100 higher than for the other planets. Concerning the changes of the semi-major axes and inclinations the results show that an increase and decrease of these elements is equally probable after an encounter. -from Authors
