I.A.150

From Li, Jing & Liao (2018)

I.A.150 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 62.814 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 4522), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000972 of each other at a top speed of 32.1, line up 138 times a period, and the computed loop closes to 5.2×10⁻²⁵.
