Moth region HS.44

From Hristov, Hristova & Tanikawa (2026)

Moth region HS.44 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 104.52 time units, published by Hristov, Hristova & Tanikawa (2026). Stable orbits from the moth-like part of the search domain, between the figure-eight and the Schubart regions. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.0349 of each other at a top speed of 5.36, line up 112 times a period, and the computed loop closes to 6.5×10⁻²⁷.
