Well sure. But my point was that for two bodies you don’t need to simulate at all, you can just get the answer for any point in time.

- phreeza 5y agoThe need for numerical simulations is completely unrelated to the predictability and/or stability of the system. If you have a Lyapunov exponent smaller than 0 everywhere, errors don't accumulate and you can simulate numerically for as long as you like.
- Grustaf 5y agoIt's not unrelated, but the implication only goes in one direction. If you have a closed form solution, that implies that you can model it completely forever, but sure the opposite is not true.
