Update 1: See the my most recent 2010 AL30 post for updates and a fly-by animation.

On Wednesday, January 13, 2010 at 12:48 GMT, a newly discovered asteroid with temporary designation 2010 AL30 will fly by the Earth at the distance of 0.000 86 AU (129,060 km; about 33% of the distance to the Moon). The asteroid has a diameter of approximately 10-25 meters and poses no risk to anyone, as not only is the calculated perigee distance quite accurate, but in a case of the encounter with Earth’s atmosphere, it would certainly break up and rain down only a few small fragments (meteorites).

At around 10 UT on January 13, the object could reach a maximum brightness of 13.8 magnitude and despite a large relative motion (about 10 arcsec/second) should be easily observable with a medium size equipment.

2010 AL30 will also have closer encounters with our Moon (January 14, 2010 at 0.001 86 AU), Mars (July 24, 2039 at 0.089 6 AU) and several close encounters with Venus (May 16, 2012, August 2, 2016, January 5, 2037, etc.)
