Total particle mass flux (g m−2 s−1) in each mass bin encountering Jupiter (Top left), Saturn (Top right), Uranus (Bottom left), and Neptune (Bottom right) at the planet’s exobase, for dust populations from Jupiter-family comets (orange), the Edgeworth-Kuiper belt (green), and Oort-Cloud comets (blue). Particles were grouped into bins based on mass, with 2 bins per decade of mass. The solid curves are from Poppe (2016), and the dashed curves were extrapolated as described in the text.
