I.B.190

From Li & Liao (2017)

I.B.190 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 187.32 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is weakly unstable (largest Floquet multiplier 2.047), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00000957 of each other at a top speed of 323, line up 400 times a period, and the computed loop closes to 2.0×10⁻²⁰.
