The Agreement Governing the Activities of States on the Moon and Other Celestial Bodies,[1] better known as the Moon Treaty or Moon Agreement, is an international treaty that turns jurisdiction of all heavenly bodies (including the orbits around such bodies) over to the international community. Thus, all activities must conform to international law (notably this includes the UN Charter).

In practice, it is a failed treaty since it has not been ratified by any nation which engages in self-launched manned space exploration or has plans to do so (e.g. the United States, Russian Federation, People's Republic of China, Japan, India and Iran) since its creation in 1979, and thus has a negligible effect on actual spaceflight.

The Moon Agreement was considered and elaborated by the Legal Subcommittee from 1972 to 1979. The Agreement was adopted by the General Assembly in 1979 in resolution 34/68. It was not until June 1984, however, that the fifth country, Austria, ratified the Agreement, allowing it to enter into force in July 1984. The Agreement reaffirms and elaborates on many of the provisions of the Outer Space Treaty as applied to the Moon and other celestial bodies, providing that those bodies should be used exclusively for peaceful purposes, that their environments should not be disrupted, that the United Nations should be informed of the location and purpose of any station established on those bodies. In addition, the Agreement provides that the Moon and its natural resources are the common heritage of mankind and that an international regime should be established to govern th exploitation of such resources when such exploitation is about to become feasible. As of 1 January 2008, 13 States have ratified, and an additional 4 have signed the Moon Agreement.
