2MASS J22501512+2325342 b
Astrophysical Synthesis & Habitability Characterization
2MASS J22501512+2325342 b is a confirmed gas giant exoplanet orbiting the star 2MASS J22501512+2325342, located approximately 186.7 light-years (57.23 parsecs) from the Solar System. First announced in 2018 by The 2 (Two) Micron All Sky Survey (2MASS) 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 9534.852 Earth masses (30 Jupiter masses). Combining its mass and radius yields a mean bulk density of 31.2 g/cm³ (an iron-enriched, high-compression rocky core), a surface gravity of 67.33 g⊕ (660.28 m/s²), and an escape velocity of 316.6 km/s.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 1600 K (+1327°C / +2421°F), 2MASS J22501512+2325342 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star 2MASS J22501512+2325342 is classified as a low-mass red dwarf of spectral type M3 with an effective photospheric temperature of 3,352 K, a radius of 0.4376 R☉, a mass of 0.4332 M☉, an estimated bolometric luminosity of 0.022 L☉. Stellar evolution modeling indicates an estimated stellar age of 0.15 Gyr. From Earth, 2MASS J22501512+2325342 shines at apparent V-band magnitude 14.784 (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).
