One of these objects was given the designation 1999 UX18 and is one of the dimmest objects in the night sky. In addition to Callirrhoe, one of these bodies names a group that contains all irregularly shaped objects that cannot form spheroids, the Ananke Group. One of the largest of these objects is home to the Valhalla and Lofn impact sites, and that body is the most heavily cratered object in the Solar System. These bodies which were studied extensively by the Pioneer 10 spacecraft also include one object which is believed to have a subsurface ocean of water. The largest of the innermost of these objects has many active volcanoes. For 10 points identify these objects which include Metis and Himelia, the four most famous of which include those discovered by Galileo, Io and Europa.
