TOI-6080 b
Astrophysical Synthesis & Habitability Characterization
TOI-6080 b is a confirmed sub-neptune exoplanet orbiting the star TOI-6080, located approximately 613.8 light-years (188.18 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 0.0823% across the stellar disk), this world measures 3.324 Earth radii (0.3 Jupiter radii) and has a measured mass of 11 Earth masses. Combining its mass and radius yields a mean bulk density of 1.65 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 1 g⊕ (9.81 m/s²), and an escape velocity of 20.3 km/s.
In its orbital architecture around TOI-6080, TOI-6080 b completes one full revolution every 8.056 Earth days.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 919 K (+646°C / +1195°F) and receiving 168.81 S⊕ (~229,753 W/m²), TOI-6080 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star TOI-6080 is classified as a stellar host with an effective photospheric temperature of 5,775 K, a radius of 1.0622 R☉, a mass of 1.01 M☉, an estimated bolometric luminosity of 1.126 L☉. From Earth, TOI-6080 shines at apparent V-band magnitude 11.178 (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).
