The asteroid -- a fuzzy dot zipping through space -- was discovered a year ago by Jaime Nomen, mild mannered dental surgeon by day, amateur astronomer by night.
It is called 2012 DA 14, and it will come scarily close to Earth on Friday, traveling from south to north, passing closest to Australia, Asia, and Eastern Europe. Closest approach is at 2:25 p.m. ET.
It will miss us by about 17,230 miles. To put that into perspective, the moon is 238,900 miles from Earth.
