Broucke R6

From Broucke (1975)

Broucke R6 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 5.1674 time units, published by Broucke (1975). Retrograde relatives of the A family, with the third body circling the other way. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.298 of each other at a top speed of 1.82, line up 12 times a period, and the computed loop closes to 4.0×10⁻³⁰.
