Abstract: The dynamics of artificial asteroids on the Trojan-like orbits around Neptuneis investigated in this paper. We describe the dependence of the orbitalstability on the initial semimajor axis a and inclination i by constructing adynamical map on the a,i-plane. Rich details are revealed in the dynamicalmap, especially a unstable gap at i=45 deg is determined and the mechanismtriggering chaos in this region is figured out. Our investigation can be usedto guide the observations.
