(5535) Annefrank is an asteroid in the main asteroid belt with a diameter of six kilometers. The asteroid was discovered by the German astronomer Karl Wilhelm Reinmuth on March 23, 1942 and was later named in memory of the Holocaust victim Anne Frank .
Annefrank moves between 2.0713 ( perihelion ) AU to 2.3537 AU ( aphelion ) in an almost circular orbit around the sun . The orbit is inclined 4.2475 ° to the ecliptic , the orbital eccentricity is 0.0638.
On November 2, 2002, the Stardust space probe flew past Annefrank 3079 km away and sent over 70 images to Earth. The images show an irregularly shaped celestial body strewn with impact craters with a very dark surface.
