TOI-941 b
Astrophysical Synthesis & Habitability Characterization
TOI-941 b is a confirmed gas giant exoplanet orbiting the star TOI-941, located approximately 859 light-years (263.39 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 0.2539% across the stellar disk), this world measures 6.512 Earth radii (0.58 Jupiter radii) and has a measured mass of 34.6 Earth masses (0.11 Jupiter masses). Combining its mass and radius yields a mean bulk density of 0.69 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 0.82 g⊕ (8.04 m/s²), and an escape velocity of 25.8 km/s.
In its orbital architecture around TOI-941, TOI-941 b completes one full revolution every 8.515 Earth days.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 982 K (+709°C / +1308°F) and receiving 220.14 S⊕ (~299,614 W/m²), TOI-941 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star TOI-941 is classified as a stellar host with an effective photospheric temperature of 5,746 K, a radius of 1.1849 R☉, a mass of 1.078 M☉, an estimated bolometric luminosity of 1.373 L☉. From Earth, TOI-941 shines at apparent V-band magnitude 11.456 (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).
