Broucke–Boggs S28

(0.3, 0.15, 2.55)

From Broucke & Boggs (1975)

Broucke–Boggs S28 (0.3, 0.15, 2.55) is a periodic orbit of the planar three-body problem: three masses in the ratio 0.3 : 0.15 : 2.55 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 1.08 of each other at a top speed of 1.36, line up 6 times a period, and the computed loop closes to 2.2×10⁻²⁵.
