Using video footage gathered from various sources and knowing the landing point of the meteor, scientists in Columbia have been able to recreate its path to Earth, including the boom-a-rang effect it had in orbiting around the sun. A separate group of researcher have pinpointed that the meteor came from an asteroid belt between Mars and Jupiter.
And closer to the scene of the impact, cross-country skiers have crisscrossed over the 31-mile-long debris field below the meteor's path, collecting more than 100 pieces of meteorite, the biggest being 2.2 pounds.
Some chunks are for sale for as much as $16,000. How much would you be willing to spend for a piece of space debris? How much would you be willing to spend now that you know it's probably 4.5 billion years old?
