ResumoThe problem of capture and scape of comets is still a controversial problem in Celestial Mechanics. The number of short-period comets (period < 200 years) seems to be larger than it should be, based in the actual flux of near parabolic comets entering the Solar System and the models knowm for the captures. In our paper, we address this problem by numerical integration of a large number of trajectories of possible comets. We use the regularized (Lamaître regularization) planar-circular-restricted-three-body-problem as our basic model. As initial conditions for our trajectoires, we choose the parameters: Jacobian constant (J), the distance Xc (from the center of mass to the point where the comet crosses the Sun-Jupiter line) and the crossing angle (0). The trajectoires were integrated backward and forward in time and we calculated the energy and the angular momentum ofthe comet before and after the encounter. Then we classify the orbits according to the effects of the close approach. Our results consist of letter-plots, which means that the plot a letter that describes the effect of the close encounter in a two-dimensional diagram having the parameter Xc in the horizontal axis and the parameter 0 in the vertical axis. We make one plot for every value of the parameter J. With those plots we make histograms to show the distribution of the pericenter distance and the semi-major axis (equivalent to orbital period) of the captured comets. We conclude that: the probability of capture has a maximum of 3,6 at J = -1,15; more than 95 of the captured comets will have pericenter distance less than 5 AU, what makes them visible when passing near their pericenter, about 70 will have an orbital period smaller than 200 years.
