      My guess, watching it turn. If it had gotten hot enough to melt, the elements would have distributed around rather evenly and it would have cooled into a rather stable spin. A rubble pile, on the other hand, will have it’s mass unevenly distributed, giving it a noticeable wobble.

      But that’s just my guess.Report
