Applying the previous model we obtain the paths of several planets of the Solar System. In addition we obtain the precession for every planet using the formula given by the Vectorial Relativity and we compare it with the values of the precession given by the GTR ( General Theory of the Relativity ). KEYWORDS: Path of Planets, VTR. INDEX I. Introduction II. Equation of the Path of a Planet III. Path of some Planets of the Solar System IV. Precession of Planets V. Conclusion References I.

The equation (1) is solved in approximate form using all the results and definitions of the vectorial Theory of the relativity [1] [6]. (a) The new definition of relativistic mass is used [6], M m 1 v c 3 () thats corrects that given by Einstein s in 195, M m 1 v c 1 (3) (b) The new definition of Relativistic Kinetic Energy is used [].
