I.A.128

From Li, Jing & Liao (2018)

I.A.128 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 159.22 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 0.0000834 of each other at a top speed of 11, line up 266 times a period, and the computed loop closes to 2.9×10⁻²³.
