Dragonfly II.16.A

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

Dragonfly II.16.A is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 95.811 time units, published by Šuvakov & Dmitrašinović (2013). Slim, elongated wings that stretch far from the centre of mass. It is unstable (largest Floquet multiplier 10.23), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000162 of each other at a top speed of 78.6, line up 96 times a period, and the computed loop closes to 2.2×10⁻²³.
