An asteroid about 20 meters wide is whipping past the Earth, only 85,000 kilometers away, just a bit higher than a communications satellite, reports the news service Spaceweather.com.
After sunset Tuesday, astronomers could see the space rock designated 2009 FH speeding through the constellation Gemini.
It is the second asteroid to cut close to Earth this month. On March 2, one labeled DD45 shot by only 72,000 kilometers away. Spaceweather.com reports that both are "Tunguska-class" size asteroids, comparable to one that exploded over Siberia in 1908.
