"Kleopatra could be the remnant of an incredibly violent collision between two asteroids that did not completely shatter and disperse all the fragments." This page also states that klopatra is metalic, and could have been the core of a larger body, but the shape is wrong shurly. I dont buy the argument that it was once two bodies that have joined by infilling. Anyone have more on this?
