Broucke–Boggs S31

(0.375, 0.3, 2.325)

From Broucke & Boggs (1975)

Broucke–Boggs S31 (0.375, 0.3, 2.325) is a periodic orbit of the planar three-body problem: three masses in the ratio 0.375 : 0.3 : 2.325 that return to their starting positions and velocities every 12.566 time units, published by Broucke & Boggs (1975). Broucke and Boggs’s 1975 survey of periodic orbits at many mass ratios, most of them reported linearly stable. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 1.17 of each other at a top speed of 1.37, line up 6 times a period, and the computed loop closes to 8.6×10⁻²⁵.
