Toutatis - Earth-Based Radar

Goldstone radar images of asteroid 4179 Toutatis

Four radar images of asteroid 4179 Toutatis created using the Goldstone DSN antennas. These images were made on 8,9,10, and 13 December 1992 when Toutatis made a closest approach (approx. 4 million km) to Earth. The radar illumination is from the top in each image, and each shows the asteroid in a different orientation. Toutatis is an irregularly shaped body roughly 4.6 x 2.4 x 1.9 km, which appears to consist of 2 bodies in contact. The large crater in the 9 December image (2nd from top) is about 700 m in diameter.
