The Moon is an astronomical body that orbits planet Earth, being Earth's only permanent natural satellite.
- In I Am Number Four, he Mogadorians have technology to emit a domed electromagnetic frequency that cancels all communication devices inside the radius, along with affecting the air and cancelling reflected moonlight.
- In Hunt for the Garde, the Moon is mentioned when Rexicus Saturnus recollects visiting the Lincoln Memorial Reflecting Pool south of Ashwood Estates.
- After Adamus Sutekh causes a brief civil war, one of the Mogadorian warships stationed over São Paulo flees Earth, believing Setrákus Ra is dead, and begins orbiting the Moon.
- As of United as One, the warship is radio silent.
- It is possible that, unless they somehow harvest resources from the Moon, the Mogadorians about the São Paulo warship will die with limited life support.
- It is also possible, while unlikely, that these Mogadorians are attempting to build a temporary colony on the Moon. Whether for pilgrimage or for military purposes is currently unknown.
