Can a nation claim the Moon as its territory?

No, the Outer Space Treaty rejects national ownership claims.

  1. Yes, after landing
  2. Yes, with a flag
  3. No, national claims are barred ✔

Why: The Outer Space Treaty says outer space and celestial bodies cannot become national territory through sovereignty, use or occupation. Planting a flag does not create ownership.

Huh, didn't know that: The treaty also makes space free for exploration and use by all states.

The Moon skipped the property listing because it was not for sale.
