The Solar System is stable on the time-scale of the existence of humans, and far beyond, given that it is unlikely any of the planets will collide with each other or be ejected from the system in the next few billion years, and that Earth's orbit will be relatively stable.
The stability of the solar system is one of the oldest problems in theoretical physics, dating back to Isaac Newton. Understanding its stability is significant because it helps explain the long-term behavior of planets and other celestial bodies in our solar system.
The most straightforward way to determine the stability of the solar system is to follow the planetary orbits for a few billion years on a computer.
An integration over 200 million years showed that the solar system, and more particularly the system of inner planets (Mercury, Venus, Earth, and Mars), is chaotic, with a Lyapunov time of 5 million years (Laskar, 1989).
The long-term orbital stability of the inner planets in our Solar System is still an open problem : the orbits of Mercury, Venus, Earth, and Mars are highly stable over the lifetime of the Solar System, even

The solar system is chaotic, but it is also stable! The fixed and linkages between the bars of a double pendulum allow for very rapid energy transfer between the arms.

Now, most planetary scientists agree that the solar system is unstable and that it is slowly tearing itself apart. The newer models also give astronomers a clearer look at the future—they show...

Thanks to the numerical experiments of the last two decades, we know now that the motion of the planets in the Solar System is chaotic, which prohibits any accurate prediction of their
