Broucke–Boggs S4

From Broucke & Boggs (1975)

Broucke–Boggs S4 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 4.2691 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 0.321 of each other at a top speed of 2.07, line up 6 times a period, and the computed loop closes to 1.1×10⁻²⁹.
