What We Found

The United States is a signatory to the 1967 Outer Space Treaty, which explicitly prohibits nations from claiming sovereignty over the moon or other celestial bodies.

Evidence

The claim that the United States is bound by a treaty preventing the national appropriation of celestial bodies is accurate. The 'Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies,' commonly known as the Outer Space Treaty, was opened for signature in 1967. Article II of this treaty states: 'Outer space, including the moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.' The United States is a party to this treaty, having signed and ratified it in 1967. This legal framework remains the cornerstone of international space law and prevents any nation from claiming the moon as its own territory.

What's Missing or Misleading

While the treaty prohibits national appropriation (sovereignty), there is ongoing international debate and legal discussion regarding the extraction and commercial use of space resources by private entities, which some argue is distinct from claiming territorial sovereignty.
