**Abstract:**

In previous works, it was established the correct equation that governs gravitational effect of a massive body, considered it with a fixed and constant mass M, on a planet of mass m = M0 /(1-v2/c2)^3/2 , moving at velocity v and momentum p, became: d^2 r/dt^2 - rw^2 +dm/(mdt) = - G, where the value of the gravitational field G exerted by the massive body on the planet’s variable mass m denoting by p0, the constant value of the linear momentum for the planet attracted by the massive body, at its nearest point (r0 ). Through these equations and the new expression of Kinetic Energy under the VTR, was obtained also in another previous work a very approximate value of Mercury’s precession. In present work we address a photon’s motion around a massive body by doing the same treatment done for any mass (m = p/c). According to this work, this is a consistent, general and natural way to attack the problem of photon’s motion.
