BH-1113

From Three Body Orbits (2026)

BH-1113 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 678.46 time units, published by Three Body Orbits (2026). Three linearly stable orbits found here in September 2026 by pushing the Broucke region past the published catalogue’s limit of T* = 800: two continue known lap sequences, one is a seventeen-fold resonant satellite of the Broucke-region orbit B1. Verified independently to 160 bits and again by this atlas’s own tool; not published elsewhere. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.00058 of each other at a top speed of 41.5, line up 726 times a period, and the computed loop closes to 1.2×10⁻²⁵. How they were found, verified and compared with the catalogues is set out in the research note.
