TOI-2092 b
Astrophysical Synthesis & Habitability Characterization
TOI-2092 b is a confirmed sub-neptune exoplanet orbiting the star TOI-2092, located approximately 576.5 light-years (176.76 parsecs) from the Solar System. First announced in 2026 by Transiting Exoplanet Survey Satellite (TESS) using the Transit detection technique (producing an estimated primary transit depth of 0.0661% across the stellar disk), this world measures 2.949 Earth radii and has a measured mass of 9 Earth masses. Combining its mass and radius yields a mean bulk density of 1.94 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 1.03 g⊕ (10.1 m/s²), and an escape velocity of 19.5 km/s.
In its orbital architecture around TOI-2092, TOI-2092 b completes one full revolution every 4.303 Earth days.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 1042 K (+769°C / +1416°F) and receiving 195.79 S⊕ (~266,474 W/m²), TOI-2092 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star TOI-2092 is classified as a stellar host with an effective photospheric temperature of 5,842 K, a radius of 1.0519 R☉, a mass of 0.956 M☉, an estimated bolometric luminosity of 1.156 L☉. Stellar evolution modeling indicates a metallicity of [Fe/H] = -0.122 dex (metal-poor relative to the Sun). From Earth, TOI-2092 shines at apparent V-band magnitude 11.295 (faint and requiring research-grade or CCD telescopic photometry) in the Northern celestial hemisphere.
Methodology: Computed using the Schulze-Makuch et al. (2011) weighted metric comparing physical interior (radius, estimated density) and surface thermal regime (escape velocity, equilibrium temperature).
