I.B.128

From Li & Liao (2017)

I.B.128 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 153.08 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 0.0000329 of each other at a top speed of 174, line up 288 times a period, and the computed loop closes to 3.2×10⁻²².
