Asteroid looks even better second time around

Asteroid 1998 WT24 safely flew past Earth on Dec. 11 at a distance of about 2.6 million miles (4.2 million kilometers, 11 lunar distances). During its flyby, NASA scientists used the 230-foot (70-meter) DSS-14 antenna at Goldstone, California, to probe it with microwave transmissions. Using this technique, they created the highest-resolution radar images of the asteroid.
