Video shows asteroid 2007 HA flying past Earth yesterday 2.5 million kilometers away. Amateur astronomer Greg Selleck filmed the flyby from his home in Madison, Wisconsin. At 13th magnitude, the space rock was an easy target for large backyard telescopes. Remarkably, this bright 300 meter near-Earth asteroid was utterly unknown only two days ago; it was discovered by MIT's LINEAR program on April 16th.
Nice!
