I.B.75

m₃ = 0.75

From Li & Liao (2017)

I.B.75 m₃ = 0.75 is a periodic orbit of the planar three-body problem: three masses in the ratio 1 : 1 : 0.75 that return to their starting positions and velocities every 142.98 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is unstable (largest Floquet multiplier 861.1), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00104 of each other at a top speed of 33, line up 196 times a period, and the computed loop closes to 5.1×10⁻²⁵.
