We derive the Doppler effect of gravitational field from mathematics and physics, and apply it to the calculation of Mercury precession. The result is consistent with general relativity.

The formula

I uploaded the article to the sciforums, you can join us to promote Newton's gravitational correction. You can also raise objections, and hope that our efforts can promote the development of natural science.

The formula

**F(v)= G*M*m/R^2 * (c - v)/c**, which is not from guess or hypothesis, but from mathematical and physical derivation. And but we need courage to admit its correctness, because it challenges Newton and Einstein. I hope this article can be read by astronomers, maybe this will be an amazing discovery.I uploaded the article to the sciforums, you can join us to promote Newton's gravitational correction.
