This video shows some examples of proposals for flags of Earth, the Moon, and Mars. It is important to note that these flags are merely proposals and are not official. There is no governmental body or organization capable of adopting flags for celestial bodies, and the Outer Space Treaty of 1967 forbids governments or organizations from doing so.

Abbreviations:
FRA = Fibits Reality Adjustment
IFOPE = International Flag of Planet Earth
