← ScienceWhich deviation occurs via Mercury's orbit when general relativity effects dominate?
A)Perihelion precession✓
B)Eccentricity fluctuations
C)Orbital inclination shift
D)Semi-major axis expansion
💡 Explanation
The perihelion of Mercury's orbit exhibits a precession because spacetime curvature near the Sun is significant leading to deviations from Newtonian gravity; therefore, perihelion precession dominates, rather than just variations in eccentricity under Newtonian perturbations.
