Moth region HS.948

From Hristov, Hristova & Tanikawa (2026)

Moth region HS.948 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 522.13 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 0.000163 of each other at a top speed of 78.4, line up 518 times a period, and the computed loop closes to 1.5×10⁻²³.
