The present terrestrial planetary system is still being disturbed by the massive jovian planets. However， the wide separation and mutual interaction among the terrestrial planets renders the disturbance ineffective; the degree of disturbance by jovian planets is O(eJ)(order of magnitude of the eccentricity of Jupiter)， since the disturbance caused by jovian planets is a forced oscillation having an amplitude of O(eJ). Heightening of eccentricity， for example O(eJ)～0.05， is far from sufficient to provoke instability in the terrestrial planets having such a wide separation as 26RH. Thus we assume that the present wide dynamical separation among terrestrial planets (> 26RH) is probably one of the most significant conditions for maintaining the stability of the planetary system over a 109-yr time-span. Our detailed analysis of the relationship between dynamical distance between planets and the instability time-scale of Solar system planetary motion is now on-going.

Although our numerical integrations span the lifetime of the Solar system， the number of integrations is far from sufficient to fill the initial phase space. It is necessary to perform more and more numerical integrations to confirm and examine in detail the long-term stability of our planetary dynamics.

這只是作者君參考的一篇文章，關於太陽系的穩定性。

還有其他論文，不過也都是英文的，相關課題的中文文獻很少，那些論文下載一篇要九美元（《Nature》真是暴利），作者君寫這篇文章的時候已經回家，不在檢測中心，所以沒有數據庫的使用權，下不起，就不貼上來了。
