Wild 2 Features

These images taken by NASA's Stardust spacecraft highlight the diverse features that make up the surface of comet Wild 2, showing a variety of small pinnacles and mesas seen on the limb of the comet and the location of a 2-kilometer (1.2-mile) series of aligned scarps, or cliffs, that are best seen in the stereo images.
