I.A.83

From Li, Jing & Liao (2018)

I.A.83 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 168.95 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 linearly stable (largest Floquet multiplier 1.006), so a small nudge only makes it wobble. The bodies pass within 0.000499 of each other at a top speed of 44.8, line up 178 times a period, and the computed loop closes to 2.9×10⁻²⁴.
