This site displays the first-ever images of a large, double asteroid once assumed to be a single asteroid called Antiope. The images were recently released by the Southwest Research Institute (SWRI). Each asteroid in the pair is approximately 50 miles across, separated by about 100 miles. This discovery was made using the W.M. Keck Observatory, Mauna Kea, Hawaii. Images of another discovery, that of a small moon orbiting the large asteroid Pulcova, is featured at this site. In addition to still images, movies show the motion of the asteroids.
