Question:
I know that current opinion on the cause for the rotational angle of Uranus is divided. What puzzles me however is how such a rotation can possibly be maintained along with an orbit which is quite "normal" in terms of other planets in the solar system. Spinning a ball, in water or on a surface, with a vertical alignment, hints at an orbit. Yet rolling a ball, a horizontal type of spin, does not seem to. Is there an explanation which can be shown, by diagram, or demonstration? It seems that what is going on with Uranus, defies either physics or gravity or both.


Replies:
What is happening with the planet Uranus does not defy gravity or any other branch of physics. It appears that sometime early in Uranus' life, it was hit by a monstrous object, a protoplanet or something, that acted as a lever that torqued the growing planet so that it now rolls about the sky on its side., and has done so ever since . May have been one, or several impacts that did the job.

Hope this helps.
