SFDs of craters produced on NEA targets with diameters of 500 m (left panel), 1 km (middle panel), and 750 m (right panel), corresponding to Bennu, Ryugu, and Didymos, respectively. Coloured solid curves show the median number of craters per Myr larger than a given diameter D for different values of the target strength Y. Black curves represent the observed crater SFDs on Bennu (Bierhaus et al. 2022), Ryugu Hirata et al. (2020), and Didymos (Barnouin et al. 2024). Shaded area in the left panel indicates the uncertainty in Bennu’s lifetime as a NEA (Ballouz et al. 2020).
