Dragonfly II.14.B

From Šuvakov & Dmitrašinović (2013). Sequences of orbits from the Belgrade three-body gallery.

Dragonfly II.14.B is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 68.991 time units, published by Šuvakov & Dmitrašinović (2013). Slim, elongated wings that stretch far from the centre of mass. It is unstable (largest Floquet multiplier 16.55), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00139 of each other at a top speed of 26.9, line up 84 times a period, and the computed loop closes to 5.3×10⁻²⁶.
