17,000 miles is close enough for me. That's closer than our GPS satellites.

"The asteroid is similar in size to the object that exploded over
Siberia, Russia, in 1908 in the Tunguska event. That explosion leveled
hundreds of square miles of land, scientists said. While asteroid 2012
DA14 could potential[ly] create such destruction if it struck the
Earth, there is absolutely no chance of an impact for the foreseeable
future, NASA officials said.

"This asteroid's orbit is so well known that we can say with
confidence that even considering its orbital uncertainties, it can
pass no closer than 17,100 miles from the Earth's surface," Yeomans
said. "No Earth impact is possible." "
