I.A.133

From Li, Jing & Liao (2018)

I.A.133 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 141.32 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 2.544), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00000584 of each other at a top speed of 414, line up 302 times a period, and the computed loop closes to 1.3×10⁻²⁰.
