Abstract
Our current understanding of the origin and evolution of NEAs is the result of several research steps done essentially over the last 30 years. J.G. Williams and J. Wisdom have been the pioneer researchers who showed that some resonances may increase the eccentricity of the asteroids, thus transporting them from the main belt to terrestrial planets crossing orbits. G. Wetherill with a large number of sophisticated Monte Carlo simulations, designed a scenario for the origin and evolution of NEAs. Furthermore, Farinella and collaborators found that a typical end-state for NEAs is the collision with the Sun, and Gladman and collaborators showed, with a large number of numerical simulations, that these collisions make the dynamical lifetime of the NEAs one order of magnitude shorter than previously believed. Even more recently, Migliorini and collaborators brought attention to the fact that asteroids can leave the main belt and reach Mars-crossing orbits also under the action of numerous weak mean motion resonances and that this mechanism could account for the origin of several among the multi-kilometer NEAs. The state of the art is still in rapid evolution. It should be possible in the close future to quantify the relative importance of the different escape routes from the main belt, and to better understand the mechanisms by which the transporting resonances are resupplied of bodies.
