Kozai Mechanism is a secular evolution that experiences the minor bodies of the Solar System 
of any orbital semiaxis. Assuming a plane and circular planetary system we numerically 
calculated the possible trajectories in the space of orbital elements (inclination, 
perihelic argument) of the particle located in different regions from the Solar System. 
These trajectories are contours of the mean hamiltonian of the particle. They appear some 
islands of stability in high eccentricities and inclinations that are explored integrating 
fictitious particles numerically. These maps formed by contours drastically change when 
imposing some resonant condition, question that we discussed in this work.
