Goldstone Radar Snags Images of Asteroid 2013 ET
Pasadena CA (JPL) Mar 20, 2013
A sequence of radar images of asteroid 2013 ET was obtained on March 10, 2013, by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif., when the asteroid was about 693,000 miles (1.1 million kilometers) from Earth, which is 2.9 lunar distances. The radar imagery suggests the irregularly shaped object is at least 130 feet (40 meters) wide. The 18 radar images were taken over a span of 1.3 hours. During that interval, the asteroid completed only a fraction of ... read more
