I.B.191

From Li & Liao (2017)

I.B.191 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 197.1 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is unstable (largest Floquet multiplier 22.07), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000133 of each other at a top speed of 86.8, line up 412 times a period, and the computed loop closes to 3.8×10⁻²³.
