It is either one or the other and > it is not GR. A full expansion of the equations of relativity applied to this situation will include a large number of terms. Given the values of the Sun's mass, the object's mass (considered to be small compared with that of the Sun) and the distance involved, almost all of those terms will be vanishingly small, and can be ignored. What's left corresponds to Kepler's third law. > > Another request: Can you tell me what is t for a semi major axis of > 50,000,000km? > I can't be bothered. Plug the values into Kepler's third law formula if you want to know. Sylvia.
