(2057) Rosemary is an asteroid of the outer main belt that was discovered on September 7, 1934 by the German astronomer Karl Wilhelm Reinmuth at the State Observatory Heidelberg-Königstuhl ( IAU code 024).
The mean diameter of the asteroid was determined to be 12.151 km (± 0.144). With an albedo of 0.124 (± 0.027) it has a rather dark surface, comparable to the albedo of the Earth's moon . The solar orbit of (2057) Rosemary is strongly elliptical with an eccentricity of 0.2344 . The asteroid is in a 3-2-1 orbit resonance with Jupiter and Saturn .
(2057) Rosemary was named after Rosemary Birky Hoffmann Scholl, the first wife of Hans Scholl (* 1942), an astronomer who worked at the Heidelberg Astronomical Computing Institute . The asteroid of the outer main belt (2959) was named Scholl after Hans Scholl .
