solar system orbits are formally chaotic as more than 3 bodies can not be predicted >The stability of the Solar System is a subject of much inquiry in astronomy. Though the planets have been stable when historically observed, and will be in the short term, their weak gravitational effects on one another can add up in unpredictable ways. For this reason (among others) the Solar System is chaotic in the technical sense of mathematical chaos theory,[1] and even the most precise long-term models for the orbital motion of the Solar System are not valid over more than a few tens of millions of years.
As uncertainties accumulate and we will possibly see butterfly effect "quantum jumps" at macro scale - in planetary orbits.
>Another project involved constructing the Digital Orrery by Gerry Sussman and his MIT group in 1988. The group used a supercomputer to integrate the orbits of the outer planets over 845 million years (some 20 per cent of the age of the Solar System). In 1988, Sussman and Wisdom found data using the Orrery which revealed that Pluto's orbit shows signs of chaos, due in part to its peculiar resonance with Neptune.[9]
If Pluto's orbit is chaotic, then technically the whole Solar System is chaotic, because each body, even one as small as Pluto, affects the others to some extent through gravitational interactions.
