I.B.19

From Li & Liao (2017)

I.B.19 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 72.298 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is unstable (largest Floquet multiplier 63.3), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0349 of each other at a top speed of 5.37, line up 72 times a period, and the computed loop closes to 1.2×10⁻²⁷.
