I.B.91

From Li & Liao (2017)

I.B.91 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 154.24 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is unstable (largest Floquet multiplier 48.08), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000199 of each other at a top speed of 70.9, line up 208 times a period, and the computed loop closes to 9.3×10⁻²⁴.
