TIC 150070085 b
Astrophysical Synthesis & Habitability Characterization
TIC 150070085 b is a confirmed sub-neptune exoplanet orbiting the star TIC 150070085, located approximately 666.6 light-years (204.37 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 0.0934% across the stellar disk), this world measures 3.62 Earth radii (0.32 Jupiter radii) and has a measured mass of 12.8 Earth masses. Combining its mass and radius yields a mean bulk density of 1.49 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 0.98 g⊕ (9.61 m/s²), and an escape velocity of 21 km/s.
In its orbital architecture around TIC 150070085, TIC 150070085 b completes one full revolution every 10.474 Earth days.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 945 K (+672°C / +1242°F), TIC 150070085 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star TIC 150070085 is classified as a stellar host with an effective photospheric temperature of 5,999 K, a radius of 1.086 R☉, a mass of 1.16 M☉, an estimated bolometric luminosity of 1.37 L☉. Stellar evolution modeling indicates an estimated stellar age of 0.135 Gyr and a metallicity of [Fe/H] = 0.087 dex (metal-rich relative to the Sun). From Earth, TIC 150070085 shines at apparent V-band magnitude 11.165 (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).
