The Stardust spacecraft flew within 3,300 kilometers of asteroid Annefrank on November 2, 2002. Prior to the encounter, little was known about the asteroid except how much light it reflected. It turned out that the brightness of Annefrank had been interpreted incorrectly, leading mission planners to expect a smaller and brighter asteroid. Its size is 6.6 by 5.0 by 3.4 kilometers.
