Moth VIIa.6.A

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

Moth VIIa.6.A is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 35.833 time units, published by Šuvakov & Dmitrašinović (2013). Symmetric moths whose wings meet along a luminous seam. It is weakly unstable (largest Floquet multiplier 5.530), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00886 of each other at a top speed of 10.6, line up 38 times a period, and the computed loop closes to 9.2×10⁻²⁷.
