Abstract
The newly discovered planetary system of the GJ 876 is stabilized by a 2:1 mean-motion resonance. We carried out numerical simulations of the GJ 876 p lanetary system for several sets of initial epochs, and investigated their stability, since this planetary system is very sensitive to an initial epoc h because of a large difference between the osculating elements and the mea n elements.
