I.B.69

From Li & Liao (2017)

I.B.69 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 129.4 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 0.000748 of each other at a top speed of 36.6, line up 144 times a period, and the computed loop closes to 4.1×10⁻²⁶.
