(a) Velocity distribution for micrometeoroids on the surface of Mercury, normalized to integrate to unity (from P. Pokorny et al. 2018). (b) Impact probability (km−1 s−1) as a function of velocity from M. J. Cintala (1992). The P. Pokorny et al. (2018) distribution includes high-velocity impacts from cometary debris, extending the impact velocity range to 130 km s−1.
