I.B.60

m₃ = 2

From Li & Liao (2017)

I.B.60 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 152.87 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is linearly stable (largest Floquet multiplier 1.009), so a small nudge only makes it wobble. The bodies pass within 0.00000507 of each other at a top speed of 726, line up 428 times a period, and the computed loop closes to 2.9×10⁻¹⁹.
