Newtonian physics correctly predicts that a planetary orbit will be an ellipse and general relativity correctly predicts that this ellipse will rotate, as was demonstrated with mercury.(adsbygoogle = window.adsbygoogle || []).push({});

The only thing that I can think of is that because the orbit is an ellipse then the planet will be experiencing different degrees of gravity as it varies it's distance from the sun and will also be travelling at different speeds, also due to the orbit being an ellipse.

So there would be time dilation due to gravity and also time dilation due to orbital speed.

Is it this time dilation that is the cause for the orbit to rotate, or is the cause of the orbital rotation due to something entirely different.
