Hum,
Five!, by Toutas!
Earth has acquired yet another "quasi-moon"; asteroid 2003 YN107...
This rock will `moon`(!) our planet for the next couple of years while it orbits the sun on a horseshoe-shaped path.
The asteroid, 2003 YN107 is probably a chunk of debris from an impact of a large space rock and the surface of our moon.
2003 YN107's orbital plane is almost the same as the earth's, but its unusual corkscrew-like path, means that it orbits sometimes ahead of us and sometimes behind...
Other "quasi-moons" are also known that loop around the earth: Cruithne, asteroid 2002 AA29, 1998 UP1 and 2000 PH5
[Cruithne = pictish tribe :-) ]
