Who owns the moon?

"NASA announced plans to work with other countries to put a permanent base on the moon by 2024. This raises an interesting question: Who owns the moon?

"Apparently there’s a legal agreement called The Outer Space Treaty that says no one can own any part of space, including the moon. But I have to think that when that treaty got signed, no one expected NASA to build nerd condos on the moon’s South Pole, aka “the only good part.” (Scott Adams)
