I.B.32

From Li & Liao (2017)

I.B.32 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 54.974 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is weakly unstable (largest Floquet multiplier 1.465), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00000461 of each other at a top speed of 466, line up 116 times a period, and the computed loop closes to 2.4×10⁻¹⁸.
