II.C.44

m₃ = 2

From Li & Liao (2017)

II.C.44 m₃ = 2 is a periodic orbit of the planar three-body problem: three masses in the ratio 1 : 1 : 2 that return to their starting positions and velocities every 96.722 time units, published by Li & Liao (2017). The largest class in the atlas: hundreds of II.C orbits for seven mass ratios. It is weakly unstable (largest Floquet multiplier 1.615), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00000878 of each other at a top speed of 551, line up 256 times a period, and the computed loop closes to 8.7×10⁻²¹.
