Which mechanism influences planetary orbits due to spacetime curvature?

A)Geodesic deviation
B)Inertial frame coupling
C)Gravitational lensing shift
D)Hawking radiation pressure

💡 Explanation

Geodesic deviation arises because gravity manifests as spacetime curvature, causing initially parallel trajectories to converge; therefore, nearby planetary orbits diverge, rather than being simple ellipses caused by direct forces and unchanging geometries.
