The determination of asteroid families is a long standing problem already present within their distribution with respect to their semi major axis. Such an histogram exhibits indeed structures, and, whereas holes resulted in the identification of the so-called Kirkwood gaps, peaks suggested the idea that asteroids might be distributed into families. This latter concept is supported by the break up theory. Within this framework the collision-induced burst of an asteroid leads in fact to what is named a family, that is, the set of fragments whose relative speeds are greater than the speed of ejection (see Housen and Holsapple, 1990 and references therein).
