astroengine writes "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 meteoroid that slammed into the atmosphere over the Russian Urals region on Feb. 15. What's more, they know what type of space rock it was — the Chelyabinsk-bound meteoroid originated from an Apollo-class asteroid (PDF). Apollo asteroids are well-known near-Earth asteroids that cross the orbit of Earth. Around 5,200 Apollo asteroids are currently known, the largest being 1866 Sisyphus — a 10 kilometer-wide monster that was discovered in 1972."

    I know Jorge! That work is quite amazing. They are working based on shadows. They measure the shadows of lampposts changing in small fractions of time, their size and angle, and do the same from very different places in Russia. The result is amazing!
