2010 AL30, Asteroid Or Space Junk, To Pay a Close Visit
astroengine writes "A near-Earth object that could be manmade has just been discovered hurtling toward us. On Wednesday (Jan. 13), an object called 2010 AL30 will fly by Earth at a distance of just 130,000 km (80,000 miles). That's only one-third of the way from here to the moon, i.e. very close. It will miss us, and if it did hit us, it wouldn't do any damage anyway, but I managed to pick up on some chatter between planetary scientists and found out that the 'asteroid,' or whatever it is, gives us a new standard: a 10-meter-wide asteroid can be detected two days before it potentially hits Earth. A pretty useful warning if you ask me."
If you can trust extrapolating the orbit backwards in time (you can't), JPL's orbital tool shows that this object had a 'close encounter' with Venus on Apr 15th, 2006. It also looks suspiciously like an Earth-Mars trajectory launched around Jan 12th, 2007. I was unable to find any corresponding launches, however.
Real Astronomers (TM) have now discounted the object being man-made, but it is interesting to speculate.
