%X A system of exact gravitational soliton solutions of Einstein's equations in vacuum is obtained. It is shown that gravitational solitons exist, which are regular everywhere, nondispersive and stable, popagating with constant velocity. Finally, The singularity and energy density of these gravitational solitons are also discussed.
