Wouldn't the KAM theorem apply to the stable orbits? But for the chaotic orbits there was some good work a few years back by Boekholt & Portegies Zwart. They built an arbitrary-precision N-body integrator and found that the results of ordinary N-body simulations are statistically identical to arbitrary precision integrations: https://arxiv.org/abs/1411.6671

Argh, just looked up Brutus and it's pretty much exactly what I wanted to do on my own after quite a lot of reading on n-body simulations and finding nothing like it out there. I was (very naively, I realise) hoping to do some original research. Oh well, time to study this intensively. Here's a link for the curious: https://arxiv.org/abs/1411.6671
