"It's very rare," Sharpton continues, "that you find an object large enough to make it through Earth's atmosphere and strike the Earth with such velocity that it produces a crater." But the 150 impact craters scientists have mapped around the globe over the past 50 years are evidence that such collisions do occur.

"For example, we found an 18-meter (59-foot) impact crater that formed on March 17, 2013, and it produced over 250 secondary impacts, some of which were at least 30 kilometers (18.6 miles) away," Speyerer told (http://www.space.com/34372-new-moon-craters-appearing-faster-than-thought.html) Space.com .
