Restricted Three-body-problem (analytical solvable): two heavy bodies with Masses M 1 and M 2 and a light one with m, and M 2 < 3. Joseph-Louis Lagrange showed that there were at least some solutions to the three body problem if we restricted the three bodies to move in the same plane and assumed that the mass of one of them was so small as to be negligible. It’s quite a feat in mathematical physics, and it could conceivably help astrophysicists understand new planetary systems.

Or rather, the Three-Body Problem is a famous example of a system which has no derivative pattern with any predictive power, no applicable algorithm that a human (or a bee) could discover to adapt successfully and turn basis uncertainty into basis risk. 1967: Ye Wenjie witnesses Red Guards beat her father to death during China's Cultural Revolution.

It is important to stress that this, and all classical chaotic systems, is completely deterministic. In a gravitational system with three or more bodies tracking position over time becomes chaotic. You calculate the updated velocity first, and then use it to update the positions - a tiny trick, but suddenly 2-body orbits are well behaved.
