I.B.171

From Li & Liao (2017)

I.B.171 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 171.3 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is unstable (largest Floquet multiplier 81.73), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000496 of each other at a top speed of 44.9, line up 252 times a period, and the computed loop closes to 8.8×10⁻²⁵.
