  Asteroid 1934 CT;1989 AC, well known as 4179 Toutatis, is an Apollo and
Mars-crosser asteroid with a chaotic orbit produced by a 3:1 resonance with
Jupiter and a 1:4 resonance with the Earth, and frequent close approaches to
the Earth. It is listed as a potential hazardous object (PHA). The aim of this
study is to investigate the possibility of 4179 Toutatis to be ejected from the
Solar System. This paper presents an orbital evolution of 4179 Toutatis in time
interval of ~300 kyr. Investigation of its orbital evolution is conducted by
using the Mercury subroutine package, where the gravitational perturbations of
eight major planets in the Solar System are considered. Over very short time
scales (~300 kyr) relative to the Solar System life time (~10 Gyr), the
asteroid 4179 Toutatis gave an example of chaotic motion that can cause
asteroid to move outward and may be followed by escaping from the Solar System.
