I.B.153

From Li & Liao (2017)

I.B.153 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 199.55 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is unstable (largest Floquet multiplier 11.05), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000385 of each other at a top speed of 51, line up 392 times a period, and the computed loop closes to 9.3×10⁻²⁵.
