Abstract
We study the evaluation of bending of light ray passing near a massive elliptical galaxy or star. To obtain this solution we used two dierent, Einsteinian and Lagrangian method. In doing this, we consider and compare the dierence deection angle between spherical and elliptical shape objects which led to appear a small but not negligible coecient as oblateness independent of mass but depend on shape and geometry of object.
