Claimed moons of Earth

Artist's conception of Earth with two moons.
2010 TK7 has a helical path (green) relative to Earth and its orbit (blue dots)
The orbits of Earth and the quasi-satellite Cruithne
When observed from Earth, Cruithne appears to orbit a point beside it.

Claims of the existence of other moons of Earth—that is, of one or more natural satellites other than the Moon that orbit Earth—have existed for some time. Several candidates have been proposed, but none have been confirmed. Since the 19th century, scientists have made genuine searches for more moons, but the possibility has also been the subject of a number of dubious non-scientific speculations as well as a number of likely hoaxes.
