2MASS J11011926-7732383 b
Astrophysical Synthesis & Habitability Characterization
2MASS J11011926-7732383 b is a confirmed gas giant exoplanet orbiting the star 2MASS J11011926-7732383. First announced in 2024 by European Space Agency (ESA) Gaia Satellite using the Imaging detection technique (resolved directly via high-contrast coronagraphic or interferometric imaging), this world measures 11.9 Earth radii (1.06 Jupiter radii) and has a measured mass of 8899.195 Earth masses (28 Jupiter masses). Combining its mass and radius yields a mean bulk density of 29.12 g/cm³ (an iron-enriched, high-compression rocky core), a surface gravity of 62.84 g⊕ (616.25 m/s²), and an escape velocity of 305.9 km/s.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 2677 K (+2404°C / +4359°F), 2MASS J11011926-7732383 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star 2MASS J11011926-7732383 is classified as a stellar host. From Earth, 2MASS J11011926-7732383 shines at apparent Gaia G-band magnitude 18.33 (faint and requiring research-grade or CCD telescopic photometry) in the Southern 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).
