On Feb. 15, the Urals region of Russia played host to a noisy cosmic visitor. A meteor entered the atmosphere and broke up over the city of Chelyabinsk, generating powerful shockwaves that slammed into the city, blowing out windows, causing 1,500 injuries and millions of dollars-worth of damage. Before it collided with Earth, however, the Chelyabinsk space rock was a 10,000 ton meteoroid and astronomers now think they know where it came from.

Helped by the extensive coverage of eyewitness cameras, CCTV footage and a fortuitous observation made by the Meteosat-9 weather satellite, Jorge Zuluaga and Ignacio Ferrin of the University of Antioquia in Medellin, Colombia, have been able to reconstruct the most likely orbit of the space rock around the sun before the Earth got in its way. What’s more, they know whattype of space rock it was.
