Throughout the Solar system, we see the same magnetospheric and ionospheric processes repeated in different combinations. Thus in some planets atmospheric interactions with the solar wind define the style of magnetosphere, whereas in others it is the co-rotation of the magnetosphere with a strong planetary magnetic field. The field is currently being given a huge stimulus by the new data from Saturn, Mars, Moon, Venus and Mercury, as well as comet and asteroid encounters. A wide range of important processes include Solar wind and rotation-driven magnetospheres, magnetospheric times and spatial scales much shorter or larger than those at Earth, magnetised and unmagnetised bodies, particle acceleration and reconnection, magnetopause and bow shock, sputtering, atmospheric escape and ion pickup, dust-plasma interactions, and interactions of plasma with moons. Both observationally and theoretically based talks are welcomed.
