摘要：We are dealing with the averaged model used to study the Lidov-Kozai effects in the motion of a massless asteriod in a spatial restricted elliptic three-body problem. The aim of our investigation is to analyze the stability of asteroid at an importantequilibria. We show that they are stable in the linear approximation. The Arnold–Moser stability theorem provides sufficient conditions under which this means stability in a nonlinear sense too. For 2:1 resonance, we show a case of instability.
