Moth IVc.12.B

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

Moth IVc.12.B is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 54.853 time units, published by Šuvakov & Dmitrašinović (2013). Moth-like shapes from a third topological class. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.00159 of each other at a top speed of 25.1, line up 84 times a period, and the computed loop closes to 3.2×10⁻²⁶.
