2MASS J22362452+4751425 b
Astrophysical Synthesis & Habitability Characterization
2MASS J22362452+4751425 b is a confirmed gas giant exoplanet orbiting the star 2MASS J22362452+4751425, located approximately 226.9 light-years (69.57 parsecs) from the Solar System. First announced in 2016 by W. M. Keck Observatory using the Imaging detection technique (resolved directly via high-contrast coronagraphic or interferometric imaging), this world measures 12.3 Earth radii (1.1 Jupiter radii) and has a measured mass of 3972.875 Earth masses (12.5 Jupiter masses). Combining its mass and radius yields a mean bulk density of 11.77 g/cm³ (an iron-enriched, high-compression rocky core), a surface gravity of 26.26 g⊕ (257.52 m/s²), and an escape velocity of 201 km/s.
❄️ Thermal Regime (Cryogenic Zone): With an equilibrium temperature of 10 K (-263°C / -441°F), surface water and volatile species on 2MASS J22362452+4751425 b would remain locked in cryogenic ice phases unless warmed by subsurface tidal or radiogenic heating.
The host star 2MASS J22362452+4751425 is classified as an orange K-type star of spectral type K7 V with an effective photospheric temperature of 4,045 K, a radius of 0.6412 R☉, a mass of 0.6 M☉, an estimated bolometric luminosity of 0.099 L☉. Stellar evolution modeling indicates an estimated stellar age of 0.12 Gyr. From Earth, 2MASS J22362452+4751425 shines at apparent V-band magnitude 12.368 (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).
