For a picture of our new "moon" - dsc.discovery.com A New Moon for Earth? March 26, 2004 — Earth has acquired a "quasi-moon" — an asteroid that will encircle our planet for the next couple of years while it orbits the sun on a horseshoe-shaped path, according to a report to be published on Saturday in New Scientist. The asteroid, 2003 YN17, "is probably a chunk of debris" from an impact between a larger space rock and the surface of the moon, the British weekly said. 2003 YN17's orbital plane is roughly the same as the earth's, but its unusual path, compounded by a corkscrew-like track, means that sometimes it is ahead of us and sometimes it is behind. "Since 1996, its path has taken it round the earth, making it a quasi-satellite. This phase will last until 2006," the report said. The finders are a team led by Paul Chodas, an asteroid specialist at NASA's Jet Propulsion Laboratory in California. Two other "quasi-moons" — temporary fellow-travellers that loop around the earth for while as they girdle the sun — have been spotted in recent years: Cluithne and asteroid 2002 AA29. dsc.discovery.com lurqer
