Like this. A change of 0.1 Solar masses in the green mass gives you very different solutions of the trajectory of a 3 body system. All the other initial conditions (momentum and position) are the same.pic.twitter.com/mB915wKtf4

0.1 solar masses are *really* much. That's orders of magnitudes more than the sum of all the masses of all planets. Jupiter alone only has 0.001 solar masses.

2nd order in planetary masses and 5th order in eccentricity and inclination: that was perturbation theory to deal with inner planets, removing the short periods from their motion, so as to have averaged differential equations which can be integrated on very long times…

This is the semila work of Laskar, which made him famous. He has published many many work on the same subject since then, and become a reference in that field. Laskar, J. (Mar. 1989), Nature 338, pp. 237–238

Similarly, Wesley Phinnigrue (1837-1906) noticed that, if he did not properly align the wheels of his hay wagon before traveling from Holt to Bodham, he could end up in Weybourne where he was wanted by its sheriff for compass tampering.
