I.A.52

From Li, Jing & Liao (2018)

I.A.52 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 107.17 time units, published by Li, Jing & Liao (2018). Class I.A orbits found with Liao’s clean numerical simulation method, for a third body of varying mass. It is weakly unstable (largest Floquet multiplier 1.323), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00317 of each other at a top speed of 17.8, line up 106 times a period, and the computed loop closes to 1.2×10⁻²⁵.
