The study of asteroid families is an important current topic. New insights obtained by dynamical considerations motivating the interest in completing the knowledge of the physics and the composition inside asteroid families. The discovery of young families offers a new frame of study of interaction between the family members, the family and the other solar system bodies, the consequence of a ˵hostile″ medium for asteroid surface, the importance of cumulative, and long-term, non-gravitational effects. The last decade has shown that long-term dynamics of family objects can be explained by accounting for new physical effects such as Yarkovsky and Yarkovsky–O΄Keefe–Radzievskii–Paddack effects. A review of these topic reveals the complexity and the importance of interdisciplinary research on these bodies. [ABSTRACT FROM AUTHOR]
