Asteroid Dynamical Families

This dataset contains the asteroid dynamical family classifications contained in Zappala, et al. (1995). These are based on the hierarchical clustering method applied to the proper elements of Milani and Knezevic (1994). 12,487 asteroids, numbered and unnumbered, are included. The dataset also includes a compilation of the historical asteroid families.
