ts of raw numerical data. the orbital motion of planets indicates long-term stability in all of our numerical integrations: no orbital crossings nor close encounters between any pair of planets took place.
3.1 general description of the stability of planetary orbits
first， we briefly look at the general character of the long-term stability of planetary orbits. our interest here focuses particularly on the inner four terresial planets for which the orbital time-scales are much shorter than those of the outer five planets. as we can see clearly from the planar orbital configurations shown in figs 2 and 3， orbital positions of the terresial
