Radar movie of near miss Asteroid DA14 2012
This is what the one that missed us on Friday February 15th 2012 looks like. Not to be confused with the large meteor that exploded over Russia on the same day Asteroid DA14 was around 130 ft long (40 metres) and overall a considerably larger beast.
Space Daily reports:
"An initial sequence of radar images of asteroid 2012 DA14 was obtained on the night of Feb. 15/16, 2013, by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif. Each of the 72 frames required 320 seconds of data collection by the Goldstone radar.
The observations were made as the asteroid was moving away from Earth. The asteroid's distance from the radar dish increased from 74,000 miles (120,000 kilometers) to 195,000 miles (314,000 kilometers).
The resolution is 13 feet (four meters) per pixel. The images span close to eight hours and clearly show an elongated object undergoing roughly one full rotation."
