ASTEROID TO BUZZ EARTH

An asteroid named "2013 TX68" will fly by Earth on March 5th as close as 17,000 km from our planet's surface. That would put it well inside the Clarke Belt of geosynchronous satellites. The space rock is about 30 meters wide, or 50% larger than the asteroid that broke up in the atmosphere over Chelyabinsk, Russia, three years ago. If an asteroid the size of 2013 TX68 were to enter Earth's atmosphere, it would likely produce an air burst with twice the energy of the Chelyabinsk event. Get the full story from NASA.
