II.C.7

m₃ = 4

From Li & Liao (2017)

II.C.7 m₃ = 4 is a periodic orbit of the planar three-body problem: three masses in the ratio 1 : 1 : 4 that return to their starting positions and velocities every 113.59 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 0.000196 of each other at a top speed of 181, line up 306 times a period, and the computed loop closes to 1.0×10⁻²⁴.
