WASP-167 b
Astrophysical Synthesis & Habitability Characterization
WASP-167 b is a confirmed gas giant exoplanet orbiting the star WASP-167, located approximately 1381.4 light-years (423.55 parsecs) from the Solar System. First announced in 2017 by Multiple Observatories using the Transit detection technique (producing an estimated primary transit depth of 0.8228% across the stellar disk), this world measures 17.71 Earth radii (1.58 Jupiter radii) and has a measured mass of 2542.64 Earth masses (8 Jupiter masses). Combining its mass and radius yields a mean bulk density of 2.52 g/cm³ (an intermediate density indicative of a deep water-ice mantle or dense volatile envelope), a surface gravity of 8.11 g⊕ (79.53 m/s²), and an escape velocity of 134 km/s.
In its orbital architecture around WASP-167, WASP-167 b completes one full revolution every 2.022 Earth days at a semi-major axis of 0.0365 AU (an ultra-close orbit less than one-seventh of Mercury's 0.387 AU distance from the Sun, where strong stellar tidal forces typically induce synchronous rotation). Its mean orbital velocity is approximately 196.4 km/s (compared to Earth's 29.8 km/s).
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 2329 K (+2056°C / +3733°F) and receiving 3,208.41 S⊕ (~4,366,646 W/m²), WASP-167 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star WASP-167 is classified as a warm F-type star of spectral type F1 V with an effective photospheric temperature of 7,000 K, a radius of 1.79 R☉, a mass of 1.59 M☉, an estimated bolometric luminosity of 6.902 L☉. Stellar evolution modeling indicates an estimated stellar age of 1.29 Gyr and a metallicity of [Fe/H] = 0.1 dex (metal-rich relative to the Sun). From Earth, WASP-167 shines at apparent V-band magnitude 10.517 (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).
