It may have been small, appearing so even in the best optical telescopes on Earth, but the flyby of asteroid 2012 DA14 was anything but a minor event to astronomers. Never feared as a threat to anyone or anything on or around our planet, DA14, about the size of half a football field, did come within 17-thousand miles of Earth, about 5-thousand miles close than many of our satellites in geosynchronous orbit. And that gave astronomers and scientists something to see and learn about, relatively up close.
