I.B.189

From Li & Liao (2017)

I.B.189 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 196.89 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 0.00000364 of each other at a top speed of 524, line up 396 times a period, and the computed loop closes to 4.9×10⁻²⁰.
