Re: Who owns the Moon? Legal question as billionaires launch into spa The moon has a treaty that distinguishes itself from other areas where Right of European Discovery* gives them a territorial claim. Because of these treaties, no state may claim the moon. But, if a private entity stakes out a share, that isn't necessarily illegal (who would enforce it anyway?). It's worth pointing out that Antarctica is indeed claimed by many countries with overlapping claims. Right now, there's very little reason to fight to assert their sovereignty, though. *It's usually called "Right of Discovery," but I decided that didn't really capture it accurately.
