Satellite-primary diameter ratio (D_s/D_p) vs. system equivalent diameter for known large (D_p > 100 km) binaries and higher-multiplicity systems. In the case where the system hosts more than one satellite, we consider here the outermost satellite. The double asteroids Antiope and Patroclus are excluded, as well as the strange asteroid Kleopatra, which likely formed its satellites through a different mechanism (Marchis et al. 2021).
