II.C.114

m₃ = 0.75

From Li & Liao (2017)

II.C.114 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 86.202 time units, published by Li & Liao (2017). The largest class in the atlas: hundreds of II.C orbits for seven mass ratios. It is linearly stable (largest Floquet multiplier 1.001), so a small nudge only makes it wobble. The bodies pass within 0.0000292 of each other at a top speed of 198, line up 178 times a period, and the computed loop closes to 1.2×10⁻²².
