I.B.61

From Li & Liao (2017)

I.B.61 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 117.65 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.00101 of each other at a top speed of 31.5, line up 124 times a period, and the computed loop closes to 1.5×10⁻²⁵.
