5535 Annefrank (/ˌænˈfræŋk/ ⓘ an-FRANK), provisional designation 1942 EM, is a stony Florian asteroid and suspected contact binary from the inner asteroid belt, approximately 4.5 kilometers in diameter. It was used as a target to practice the flyby technique that the Stardust space probe would later use on the comet Wild 2.[8]

The asteroid was discovered 23 March 1942, by German astronomer Karl Reinmuth at Heidelberg Observatory in southwest Germany.[11] It was named after Anne Frank, a victim of the Holocaust.[2]
