II.C.141

m₃ = 0.75

From Li & Liao (2017)

II.C.141 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 144.41 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 0.0000466 of each other at a top speed of 157, line up 240 times a period, and the computed loop closes to 4.5×10⁻²³.
