TOI-6000 b
Astrophysical Synthesis & Habitability Characterization
TOI-6000 b is a confirmed terrestrial exoplanet orbiting the star TOI-6000, located approximately 247.1 light-years (75.77 parsecs) from the Solar System. First announced in 2025 by Transiting Exoplanet Survey Satellite (TESS) using the Transit detection technique (producing an estimated primary transit depth of 0.0514% across the stellar disk), this world measures 0.94 Earth radii and has a measured mass of 0.779 Earth masses. Combining its mass and radius yields a mean bulk density of 5.17 g/cm³ (a terrestrial silicate-iron composition comparable to Earth (5.51 g/cm³)), a surface gravity of 0.88 g⊕ (8.63 m/s²), and an escape velocity of 10.2 km/s.
In its orbital architecture around TOI-6000, TOI-6000 b completes one full revolution every 0.449 Earth days.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 1120 K (+847°C / +1557°F) and receiving 258.75 S⊕ (~352,156 W/m²), TOI-6000 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star TOI-6000 is classified as a stellar host with an effective photospheric temperature of 3,419 K, a radius of 0.38 R☉, a mass of 0.37 M☉, an estimated bolometric luminosity of 0.018 L☉. From Earth, TOI-6000 shines at apparent V-band magnitude 15.454 (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).
