Possible risks of eBay sales of Chelyabinsk meteorite fragments

Fragments of a meteorite which fell in the Chelyabinsk Region in mid-February have surfaced on eBay. Although sales of the meteorite fragments are brisk, Russian lawyers have not yet decided whether or not this trade is legal. Moreover, they are continuing to debate whether meteorite fragments should be classified as mushrooms, treasure, or cultural landmarks. Depending on this classification, sellers and buyers alike could be brought to account, and may even face criminal charges.

Attack By Chondrite: Scientists ID Russian Meteor

The meteor that caused at least 1,000 injuries in Russia after a startling and powerful daytime explosion one week ago has been identified as a chondrite. Russian scientists who analysed fragments of the meteor, whose large size and well-documented impact made it a rarity, say that its composition makes it the most common type of meteor we encounter here on Earth.

Title: A preliminary reconstruction of the orbit of the Chelyabinsk Meteoroid
Authors: Jorge I. Zuluaga, Ignacio Ferrin

In February 15 2013 a medium-sized meteoroid impacted the atmosphere in the region of Chelyabinsk, Russia. After its entrance to the atmosphere and after travel by several hundred of kilometres the body exploded in a powerful event responsible for physical damages and injured people spread over a region enclosing several large cities. We present in this letter the results of a preliminary reconstruction of the orbit of the Chelyabinsk meteoroid. Using evidence gathered by one camera at the Revolution Square in the city of Chelyabinsk and other videos recorded by witnesses in the close city of Korkino, we calculate the trajectory of the body in the atmosphere and use it to reconstruct the orbit in space of the meteoroid previous to the violent encounter with our planet. In order to account for the uncertainties implicit in the determination of the trajectory of the body in the atmosphere, we use Monte Carlo methods to calculate the most probable orbital parameters. We use this result to classify the meteoroid among the near Earth asteroid families finding that the parent body belonged to the Apollo asteroids. Although semimajor axis and inclination of the preliminary orbit computed by us are uncertain, the rest of orbital elements are well constrained in this preliminary reconstruction.
