Mercury's Orbital Mystery

Mercury's orbit exhibits a precession that is 7% faster than predicted by Newtonian physics, leading to various hypotheses that ultimately failed to explain this anomaly. General relativity successfully accounts for this discrepancy, demonstrating that orbits in a two-body system do not form perfect ellipses due to the curvature of space and time caused by mass. This unique behavior is particularly pronounced for Mercury, making it a key experimental validation of general relativity.
