• Planets condense for the same reason as stars: a "like-likes-like" body force in a dusty plasma.
• Rotation within stellar systems is due to the movement of the matter through an external magnetic field, which generates a Lorentz force.
• If gravity is sufficient, charges are separated into CFDLs.
• If other bodies are close enough to generate tidal forces, there will be electric currents across the boundaries of the double-layers.
• An internal heat source under a frozen crust can result in volcanism.
