Does General Relativity predict Mercury's orbital precession without other planets?
From Newtonian mechanics, the precession of Mercury can be calculated by taking into account the gravitational pull of other planets. From that, I assume that in the absence of external planets, ...

How do we interpret measurements of Mercury's position?
When scientists measured the position of Mercury in the 18th century, they interpreted the results assuming a Euclidean background, because they did not know general relativity. So they measured $r$ ...

Would Newton's law in the solar system be independent from a presumed different fundamental gravitational law? [closed]
A thought experiment:
Let's assume the gravitational field of a black hole without any neighbors would be stronger than the Schwarzschild metric in the Newtonian limit.
Now, we let a solar system (sun ...

What are modern solar system applications of GR where approximation methods fail? [closed]
It is often stated that general relativity (GR) provides the most accurate description of gravitational phenomenon. In most undergraduate and even graduate textbooks this idea is reinforced by ...
