Abstract
The orbits of thirty two plutinos that are presently in the 3:2 mean
motion resonance with Neptune have been integrated numerically and accurately
to 108 years into the future. Fourteen of them are found in unstable
orbits after encountering Neptune or Pluto. Six of eighteen plutinos with
stable orbits are in the Kozai resonance or around its separatrix zone. No node
to node, perihelion to perihelion secular resonance or the so called 1:1 super
resonance are found.
Key words: Kuiper belt, Oort cloud -- minor planets, asteroids
