Dynamical analysis on the transitivity of Jupiter Family Comets to Near-Earth Asteroids

The purpose of this research is to identify the contribution of JFC (Jupiter Family Comet) population to NEA (Near-Earth Asteroid) region by integrating their orbits forward in time. To test and compare the statistics we also integrated NEAs having Tisserand parameters from 2 to 3 and their clones backward in time. As a result, 31.9% of orbits turned out to be Earth-crossing orbits for forward integrations while 66.7% of NEAs reached JFC region for backward integrations. From another point of view, when the number of chosen body population is considered; 304 JFC region body is possibly going to reach NEA orbits, 254 NEA region body look like come from JFC region in a comparable time interval. These results substantially support each other.
