ABSTRACT: The gravitational deflection angle of celestial bodies travelling near the sun with large eccentricity was derived using the extended Newtonian theory (ENET) and Einstein general theory of relativity (GTR). It was found that the non-Newtonian gravitational deflection of celestial bodies for ENET is 1.5 times the prediction of GTR. The deflection angle of the photon however coincided with the light deflection of GTR. It was also found that the photon’s gravitational deflection obeys (as in GTR) an ODE which is a special case of the one for relativistic celestial bodies.
