I.B.73

m₃ = 0.75

From Li & Liao (2017)

I.B.73 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 84.361 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.0000918 of each other at a top speed of 112, line up 196 times a period, and the computed loop closes to 2.8×10⁻¹⁷.
