I.B.37

m₃ = 2

From Li & Liao (2017)

I.B.37 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 140.76 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.0000479 of each other at a top speed of 236, line up 268 times a period, and the computed loop closes to 1.5×10⁻²³.
