I.B.60

From Li & Liao (2017)

I.B.60 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 93.019 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is unstable (largest Floquet multiplier 85.69), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000715 of each other at a top speed of 37.4, line up 124 times a period, and the computed loop closes to 4.0×10⁻²⁵.
