I.B.82

From Li & Liao (2017)

I.B.82 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 152.29 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is unstable (largest Floquet multiplier 220.4), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00132 of each other at a top speed of 27.5, line up 192 times a period, and the computed loop closes to 4.5×10⁻²⁵.
