This symposium was devoted to the so-called minor bodies in the Solar System, and their mutual interrelationships. Asteroids, comets and meteors provide essential information on the history of the Solar System, starting with the early phases of planetary formation, until the present epoch. Different evolutionary processes have shaped the physical characteristics of the populations of minor bodies. Among them, collisional phenomena have played an essential role, as has been generally recognized by modern planetary research. This symposium was one step in the effort to sketch a general unifying scenario of the properties of the different populations of minor bodies, which are generally studied by separate scientific communities. In particular, the most recent findings on the interrelationships between asteroids, comets and meteoroids suggest that an interdisciplinary approach should be preferred. Only in this way can the properties of different populations of minor bodies be interpreted in the framework of a coherent picture of the history and evolution of the Solar System.
