Moth VIIa.13.B

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

Moth VIIa.13.B is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 95.073 time units, published by Šuvakov & Dmitrašinović (2013). Symmetric moths whose wings meet along a luminous seam. It is unstable (largest Floquet multiplier 13.83), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0286 of each other at a top speed of 5.92, line up 82 times a period, and the computed loop closes to 3.3×10⁻²⁷.
