Asteroid looks even better second time around
Asteroid 1998 WT24 safely flew past Earth on 11 December at a distance of about 2.6 million miles (11 lunar distances). During its flyby, NASA scientists used the 230-foot (70-metre) DSS-14 antenna at Goldstone, California, to probe it with microwave transmissions. Using this technique, they created the highest-resolution radar pictures of the asteroid — 2.5 times better than when it was last imaged, 14 years ago.
