The PDCO formalizes the company’s present program for detecting and monitoring near-earth objects (NEOs), which NASA has been learning for the reason that 1970s.
The area rock that streaked throughout the skies of Southern Africa was a lot smaller than the meteor that exploded over Chelyabinsk, Russia in 2013, injuring greater than 1,000 folks, which was estimated to be about 56 toes large.
