I.B.108

From Li & Liao (2017)

I.B.108 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 155.68 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is unstable (largest Floquet multiplier 46.31), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00217 of each other at a top speed of 21.5, line up 232 times a period, and the computed loop closes to 2.8×10⁻²⁵.
