Radar Images of Asteroid 2005 WK4
Pasadena CA (JPL) Aug 20, 2013
A collage of radar images of near-Earth asteroid 2005 WK4 was generated by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif., on Aug. 8, 2013. The asteroid is between 660 and 980 feet (200 and 300 meters) in diameter; it has a rounded and slightly asymmetric shape. As it rotates, a number of features are evident that suggest the presence of some flat regions and a bulge near the equator. The data were obtained between 12:40 and 7:10 a.m. PDT (3:40 ... read more
