Extremetech: On Friday, asteroid 2012 DA14 will pass within 17,200 (27,700km) of Earth. DA14 is about 50 meters wide, and will be the closest ever fly-by of a celestial body that astronomers have known about in advance — at a distance of 17,200 miles, DA14 will actually travel inside the orbit of Earth’s geosynchronous satellites.
