Radar image of asteroid Toutatis taken by NASA's Goldstone Solar System Radar on December 12 and 13, 2012.

On December 12, 2012, the day of its closest approach to Earth, the 3-mile long Toutatis was 4.4 million miles away. In these radar images, the elongated, irregularly shaped object shows ridges and craters and a very slow, tumbling rotational state, rotating on its long axis every 5.4 days.

See a short, 64 frame video of the asteroid Toutatis generated from data taken by Goldstone's Solar System Radar.
