I.B.101

From Li & Liao (2017)

I.B.101 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 172.32 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is unstable (largest Floquet multiplier 41.1), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000552 of each other at a top speed of 42.6, line up 220 times a period, and the computed loop closes to 8.9×10⁻²⁵.
