The Sun, Moon and Antimoon are all metallic massice discs, subject to photoelectric suspension in relation to the Earth's iron core.
Does massice mean that they are 'charged' objects?
Massice is a term which denotes something being the subject of charge repulsion. A massice disc is a disc which is of like charge to a base object which it is in a repulsive relation to.
When Alpha decay occurs, for example, the ejected helium nucleus is a massice object in relation to the main nucleus. In that case, it is a massice particle, not a massice disc (obviously). The relation between the Alpha particle and the other nucleus is electrostatic force, so the smaller "repulsed" object can be described as being massice.
