Asteroid Flyby
2 Mar 2009

Asteroid 2009 DD45 zipped past Earth today, March 2nd at 1340 UT, about 72,000 km (0.00048 AU) away. That's only twice the height of a geostationary communications satellite. The 35-meter-wide space rock is similar in size to the Tunguska impactor of 1908, but today there was no danger of a collision--just a close shave. Experienced amateur astronomers can track the asteroid receding from Earth using this ephemeris.

Movies: from Albert Quijano Vodniza of the Narino Observatory in Colombia; from Dave Herald of Canberra, Australia.
