“Using radar data, scientists from NASA’s Jet Propulsion Laboratory created this six-frame movie of asteroid 2005 YU55. The data was obtained Nov. 7, 2011 using NASA’s Goldstone Solar System Radar (located at the Deep Space Network facility in Goldstone, Ca.) At the time, the space rock was approximately 860,000 miles (1.38 million kilometers) away from Earth. At its closest approach on Nov. 8, 2011, YU55 will be about 200,000 miles from Earth. It poses no threat.
Resolution is 4 meters per pixel.
The movie is looped 5 times. “
