Will Earth at some point stop rotating anti-clockwise, stay still, and then rotate clockwise?

No. This would require some force imposed externally. Momentum is a wonderful thing.

  • $\begingroup$ Maybe if one of the larger centaurs gets perturbed into the inner system and Earth gets unlucky enough to suffer an oblique impact? Not sure that would count as "stay still and then rotate clockwise" though. $\endgroup$ – antispinwards Jan 26 '19 at 22:54
