I.B.118

m₃ = 0.75

From Li & Liao (2017)

I.B.118 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 184.87 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is linearly stable (largest Floquet multiplier 1.002), so a small nudge only makes it wobble. The bodies pass within 0.00000483 of each other at a top speed of 486, line up 400 times a period, and the computed loop closes to 9.9×10⁻²¹.
