– The Search Is on for Meteorite (Wall Street Journal , Feb 19, 2013):
The meteor that crashed to earth in Russia was about 55 feet in diameter, weighed around 10,000 tons and was made from a stony material, scientists said, making it the largest such object to hit the Earth in more than a century.
Large pieces of it have yet to be found. However, a team from Ural Federal University, which is based in Yekaterinburg, collected 53 fragments, the largest of which was 7 millimeters, according to Viktor Grokhovsky, a scientist at the university.
It is the largest reported meteor since the one that hit Tunguska, Siberia, in 1908, according to the National Aeronautics and Space Administration. The U.S. agency’s new estimate of the meteor’s size was a marked increase from its initial one.
