I.B.185

From Li & Liao (2017)

I.B.185 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 173.09 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is weakly unstable (largest Floquet multiplier 1.058), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00000832 of each other at a top speed of 347, line up 340 times a period, and the computed loop closes to 1.6×10⁻¹⁶.
