Density distribution of our large programme asteroid targets. The density distribution appears strongly bimodal (see text) with volatile-poor bodies on the left of the gray zone and volatile-rich bodies on its right. Two multiple systems (93 Minervaand 107 Camilla; Marchis et al. 2013; Pajuelo et al. 2018) imaged outside of our observing program were also added because of their accurate density determination. Asteroids are grouped following their spectral classification. The relativesizes of the dots follow the relative diameters of the bodies in logarithmic scale. Error bars are one sigma. In the center of the figure, the gray zone shows the average density of the main asteroid groups (left) and of their likely meteoritic analogs (right).
