These two radar images of near-Earth asteroid 2003 SD220 were obtained on Dec. 18 and 19 by coordinating observations with the Arecibo Observatory's 1,000-foot (305-meter) antenna in Puerto Rico and the National Science Foundation's (NSF) 330-foot (100-meter) Green Bank Telescope in West Virginia. The radar images reveal the asteroid is at least one mile (1.6 kilometers) long.
