I.B.62

m₃ = 2

From Li & Liao (2017)

I.B.62 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 150.82 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is weakly unstable (largest Floquet multiplier 1.346), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00001 of each other at a top speed of 516, line up 436 times a period, and the computed loop closes to 6.3×10⁻²¹.
