I.B.16

m₃ = 2

From Li & Liao (2017)

I.B.16 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 70.118 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 0.00018 of each other at a top speed of 122, line up 136 times a period, and the computed loop closes to 6.8×10⁻²⁴.
