II.C.135

m₃ = 0.75

From Li & Liao (2017)

II.C.135 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 131.29 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 1.000), so a small nudge only makes it wobble. The bodies pass within 0.00000272 of each other at a top speed of 649, line up 226 times a period, and the computed loop closes to 5.1×10⁻²¹.
