I.A.54

From Li, Jing & Liao (2018)

I.A.54 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 112.97 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 unstable (largest Floquet multiplier 186.2), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0193 of each other at a top speed of 7.21, line up 114 times a period, and the computed loop closes to 3.8×10⁻²⁷.
