Neptune: Rocking The Dreidel

When it come to making your head spin, Jupiter revolves on its axis in less than 10 hours. Up until now, it was the only gas planet in our solar system that had an accurate spin measurement. But grab your top and cut it loose, because University of Arizona planetary scientist Erich Karkoschka has clocked Neptune cruising around at a cool 15 hours, 57 minutes and 59 seconds.

Yes, right at the edge of the solar system.  And man made!
