I.B.51

From Li & Liao (2017)

I.B.51 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 89.281 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is weakly unstable (largest Floquet multiplier 6.479), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000232 of each other at a top speed of 65.7, line up 180 times a period, and the computed loop closes to 1.1×10⁻²⁴.
