I.A.185

From Li, Jing & Liao (2018)

I.A.185 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 164.79 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 1.000), so a small nudge only makes it wobble. The bodies pass within 0.00000745 of each other at a top speed of 366, line up 358 times a period, and the computed loop closes to 1.1×10⁻¹⁷.
