On November 2, 2002, the Stardust spacecraft flew by Asteroid 5535 Annefrank. This image of the asteroid was taken by the Stardust spacecraft just prior to closest approach. The gray scale figure on the right show a partially illuminated, highly irregularly shaped asteroid, typical of all small bodies imaged in our solar system. The STARDUST camera resolution was sufficient to show that Annefrank was about 8 km in length, twice the predicted size from Earth-based observations. The surface reflects about 10% to 20% of the sunlight, slightly less than predicted. A few craters many hundreds of meters are seen as well as surface brightness variations due to changes in solar illumination as well as albedo variation. These variations are exaggerated in the false color image to the left. Both images have been digitally enhanced and resampled.
