GSC 06214-00210 b
Astrophysical Synthesis & Habitability Characterization
GSC 06214-00210 b is a confirmed gas giant exoplanet orbiting the star GSC 06214-00210, located approximately 353.9 light-years (108.5 parsecs) from the Solar System. First announced in 2010 by Palomar Observatory using the Imaging detection technique (resolved directly via high-contrast coronagraphic or interferometric imaging), this world measures 20.176 Earth radii (1.8 Jupiter radii) and has a measured mass of 5000 Earth masses (15.73 Jupiter masses). Combining its mass and radius yields a mean bulk density of 3.36 g/cm³ (an intermediate density indicative of a deep water-ice mantle or dense volatile envelope), a surface gravity of 12.28 g⊕ (120.43 m/s²), and an escape velocity of 176.1 km/s.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 2300 K (+2027°C / +3681°F), GSC 06214-00210 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star GSC 06214-00210 is classified as an orange K-type star of spectral type K7 with an effective photospheric temperature of 4,200 K, a radius of 0.9048 R☉, a mass of 0.9 M☉, an estimated bolometric luminosity of 0.229 L☉. Stellar evolution modeling indicates an estimated stellar age of 0.005 Gyr and a metallicity of [Fe/H] = -0.06 dex (near-solar heavy-element abundance). From Earth, GSC 06214-00210 shines at apparent V-band magnitude 12.416 (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).
