General Relativity, the Schwarzschild Solution, and the Precession ...

The precession of the perihelion of Mercury is
measured to be 5600 arc seconds per
century.
Newton’s equations, accounting for
gravitational interaction with other planets,
Mercury’s rotation, and the fact that Earth is
not an inertial reference frame, predicts 5557
arc seconds per century– off by 43.
GR accurately accounts for discrepancy.
