Abstrakt

In this study we determined the width of the "stable" region of Pluto's

orbit in three different models: the spatial circular and the elliptic

restricted three body problem and a model of the outer solar system

consisting of the Sun, Jupiter, Saturn, Uranus, Neptune and Pluto. Both,

the examination of the orbital elements and the computations of the

Lyapunov Characteristic Exponents yielded to a width of the "stable"

zone of about 0.7 AU for the semi-major axis. In this context "stable"

means that no significant changes of the orbital elements have been

found within the integration time.
