Velocity distributions averaged throughout Venus’ orbit in terms of meteoroid mass input, expressed in kg m⁻² s⁻¹, and as a function of the impact velocity for the JFCs (a), the ASTs (b), the HTCs (c), and the OCCs (d). The solid lines in each panel illustrate the overall orbital average for the four meteoroid populations. The dashed and dashed–dotted lines in the four panels represent the meteoroid mass influxes for the diameter intervals listed in the captions.
