If the gravitation has very very tiny deviation from inverse square law！

If the gravitation has very very tiny deviation from inverse square law！our solar system became unstable? If so ,how long people on the Earth can notice it?

It does have a tiny deviation, and it doesn't make much difference. The planets have a much larger effect on perturbing the Earth's orbit than relativistic corrections.

 

[Chronos]

What deviation from GR did you have in mind? I don't see any.

Perhaps Phrak is talking about the pioneer anomaly?
