I’m wondering whether the moon’s mass makes it analogous to a charged capacitor or an uncharged capacitor.
There isn’t an answer to that unless we specify how we intend to consider using the moon. For most part it isn’t analogous to either kind of capacitor but we can construct scenarios for either case I expect.
We could, for example, use the moon to store either gravitational or kinetic energy. That would make it fairly charged (but leaking charge over time...)
We could use the moon to store heat energy --> it’s uncharged.
As for direct annihilation of the mass to release energy… would you consider that to be analogous to a ‘capacitor’? Sounds like more of a ‘battery’ to me.
