I.B.68

m₃ = 0.75

From Li & Liao (2017)

I.B.68 m₃ = 0.75 is a periodic orbit of the planar three-body problem: three masses in the ratio 1 : 1 : 0.75 that return to their starting positions and velocities every 86.677 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is linearly stable (largest Floquet multiplier 1.007), so a small nudge only makes it wobble. The bodies pass within 0.0000503 of each other at a top speed of 151, line up 184 times a period, and the computed loop closes to 8.9×10⁻¹⁷.
