| Our main goal in this work is to give an explanation of transport in the
solar system based in dynamical systems theory. More concretely
we consider (as a first approximation) different bicircular problems
(i.e. Sun, Jupiter, a planet and an infinitesimal mass), we take
{\sl natural} periodic orbits which are unstable and we study
their invariant manifolds as well as the existence
of possible heteroclinic connections. The role that these
particular trajectories
play in relation with transport from exterior planets
to the inner ones is discussed. Finally, some comments
concerning a more realistic model of the Solar System are given
and dynamical substitutes of invariant objects (from simpler models)
are obtained.
