Broucke–Boggs S21

(0.033, 0.03, 2.937)

From Broucke & Boggs (1975)

Broucke–Boggs S21 (0.033, 0.03, 2.937) is a periodic orbit of the planar three-body problem: three masses in the ratio 0.033 : 0.03 : 2.937 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 0.882 of each other at a top speed of 1.44, line up 6 times a period, and the computed loop closes to 5.6×10⁻²⁵.
