I.A.105

From Li, Jing & Liao (2018)

I.A.105 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 113.5 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 1.309), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0000969 of each other at a top speed of 102, line up 230 times a period, and the computed loop closes to 4.3×10⁻²⁴.
