5535 Annefrank is an inner main belt asteroid, and member of the Augusta family. It was discovered by Karl Reinmuth in 1942. It is named after Anne Frank, the German-Jewish diarist who died in a concentration camp (the name was not chosen until long after World War II).
In 2002, the Stardust space probe flew past Annefrank at a distance of 3079 km. Its images show the asteroid to be 6.6 × 5.0 × 3.4 km in diameter, twice as big as previously thought, and of an irregular shape with craters. From the photographs, the albedo of Annefrank was computed to be 0.24.
