Small correction, but I can't resist: Comets, like most matter, are electronically balanced electromagnetic energy balls, i.e. have no net charge* but plenty of charges. ;) * Of course they can pick up a charge from, e.g. collecting solar wind... I'm not an astrophysicist so I can't say how big it would be.
