Figure-8 satellites
Stable orbits found by an exhaustive search of the figure-eight’s neighbourhood: each traces the eight with extra loops and twists, and every one is linearly stable to 40 digits.
Figure-8 satellites are periodic solutions of the planar three-body problem. The atlas holds 196 of them, with periods from 73.74 to 857.6, all with equal masses; all of them are linearly stable. They come from Hristov, Hristova & Tanikawa (2026), An extensive search for stable periodic orbits of the equal-mass zero angular momentum three-body problem. Every orbit is precomputed to machine precision and plays one period at a time; open one to watch it, nudge it or rate it.
