Do you have any links about the relative potential of planets ?

I have a book that is still packed from my latest move. The theory is that since charged particles from the sun result in an electric current and since planets with varying characteristics (distance, size, magnetic field, etc, deflect charged particles differently, the charge on varying planets must necessarily be different. Space probes have measured the electric potential near planets and moons and one has been damaged by the intense electric fields near a moon but not in space. But think about it. Since the electric potential is not the same at different points on earth, it is likely impossible to be a fixed value anywhere else. (There are lightning discharges on the surface of Jupiter.)

On the other hand electrons move quite easily in vacuum this was used
in radio not so long ago.

Space probes have measured the density of free electrons in space. There are simply not enough electrons there to call space a conductor. There is something there, for sure, but it is not conventional matter. Apparently, the "aether" consists of dark matter.
