Initially reported as brown dwarf + exoplanet host, HD 202206 was revisited as a binary system with an inner very low-mass red dwarf companion and an outer circumbinary planet straddling the H-D burning limit (Benedict & Harrison 2017).
A new stability analysis by Cao et al. (2026) instead favours former orbital solution with two coplanar substellar companions, an inner brown dwarf and an outer gas giant planet.
