1036 Ganymed (pronounced /ˈɡænɨmɛd/) is the largest Amor asteroid. It was discovered by Walter Baade on October 23, 1924 and is named after Ganymede, the Trojan prince turned god whom Zeus designated the cupbearer to the Greek gods. Jupiter's moon Ganymede is also named after that individual. Ganymed is about 32 km in diameter and is an S-type asteroid, meaning that it is relatively reflective and composed of iron- and magnesium-silicates. It is also a Mars-crosser asteroid. In 1998, radar observations of Ganymed by the Arecibo radio telescope produced images of the asteroid, revealing a roughly spherical object. One occultation of a star by Ganymed was observed from California on August 22, 1985.
