Short summary
The Sun ejects a stream of charged particles into space that have to flow around planets like Venus. We quantify how this flow varies with spatial location using spacecraft measurements of the particles and magnetic field taken over several years. We find that this flow is connected to interactions with the heavier charged particles that originate from Venus’ upper atmosphere. These interactions are not unique to Venus, so we compare our results to similar studies at Mars.
