Schubart region HS.876

From Hristov, Hristova & Tanikawa (2026)

Schubart region HS.876 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 273.46 time units, published by Hristov, Hristova & Tanikawa (2026). Stable orbits that pass extremely close to a binary collision, descended from Schubart’s rectilinear orbit. They needed 100-digit arithmetic to find. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.000011 of each other at a top speed of 301, line up 522 times a period, and the computed loop closes to 2.3×10⁻²⁰.
