Multiple systems in the NEA population, classified according to their group, as a function of the primary radius and of the separation of the bodies (JPL/NASA). Currently, there are about 46 known multiple systems, where 2 of them are triple systems (tagged with the letter “T”). In the diagram the data of 37 multiple systems are presented. For the other binaries, the separations of the bodies were not determined well yet. In the label on the top is the percentage of asteroids of each group related to the total of bodies considered in the diagram – 37 asteroids. For the triple systems the position of the most external satellite was considered. The black line indicates the limit of 0.06 primary’s Hill radius, which corresponds to the 5 km limit of separation between the primary and the satellite.
