TOI-2337 b
Astrophysical Synthesis & Habitability Characterization
TOI-2337 b is a confirmed gas giant exoplanet orbiting the star TOI-2337, located approximately 1748.3 light-years (536.05 parsecs) from the Solar System. First announced in 2022 by Transiting Exoplanet Survey Satellite (TESS) using the Transit detection technique (producing an estimated primary transit depth of 0.0825% across the stellar disk), this world measures 10.088 Earth radii (0.9 Jupiter radii) and has a measured mass of 508.525 Earth masses (1.6 Jupiter masses). Combining its mass and radius yields a mean bulk density of 2.73 g/cm³ (an intermediate density indicative of a deep water-ice mantle or dense volatile envelope), a surface gravity of 5 g⊕ (49.03 m/s²), and an escape velocity of 79.4 km/s.
In its orbital architecture around TOI-2337, TOI-2337 b completes one full revolution every 2.994 Earth days. With a near-circular eccentricity of e = 0.019, the planet experiences minimal orbital distance variation.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 1272 K (+999°C / +1830°F) and receiving 619.58 S⊕ (~843,250 W/m²), TOI-2337 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star TOI-2337 is classified as a stellar host with an effective photospheric temperature of 4,780 K, a radius of 3.22 R☉, a mass of 1.325 M☉, an estimated bolometric luminosity of 4.856 L☉. Stellar evolution modeling indicates an estimated stellar age of 4.9 Gyr and a metallicity of [Fe/H] = 0.39 dex (metal-rich relative to the Sun). From Earth, TOI-2337 shines at apparent V-band magnitude 12.524 (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).
