COMET BORRELLY

Image 1: A composite of images taken by NASA's Deep Space 1 spacecraft when it flew by comet Borrelly on Sept. 22, 2001, shows features of the comet's nucleus, dust jets escaping the nucleus and cloudlike "coma" of dust and gases surrounding the nucleus. False color is used to reveal details of the jets and coma.

This was the final image of the nucleus of comet Borrelly, taken just 160 seconds before Deep Space 1's closest approach to it. This image shows the 8-km (5-mile) long nucleus about 3417 kilometers (over 2,000 miles) away. (2001) Image Credit: NASA/JPL More Information: NASA home page
