HD 110014 b
Astrophysical Synthesis & Habitability Characterization
HD 110014 b is a confirmed gas giant exoplanet orbiting the star HD 110014, located approximately 328.6 light-years (100.76 parsecs) from the Solar System. First announced in 2009 by La Silla Observatory using the Radial Velocity detection technique (measuring periodic Doppler reflex motion in the host star's spectrum), this world measures 12.4 Earth radii (1.11 Jupiter radii) and has a measured mass of 3524.59 Earth masses (11.09 Jupiter masses). Combining its mass and radius yields a mean bulk density of 10.19 g/cm³ (an iron-enriched, high-compression rocky core), a surface gravity of 22.92 g⊕ (224.77 m/s²), and an escape velocity of 188.6 km/s.
In its orbital architecture around HD 110014, HD 110014 b completes one full revolution every 835.477 Earth days (2.29Julian years) at a semi-major axis of 2.14 AU (corresponding to the middle-system regime between Mars at 1.52 AU and Jupiter at 5.20 AU). Its mean orbital velocity is approximately 27.9 km/s (compared to Earth's 29.8 km/s). The planet follows a highly eccentric trajectory (e = 0.462, swinging from 1.1513 AU at periapsis out to 3.1287 AU at apoapsis), pointing to past dynamical scattering or secular gravitational perturbations.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 670 K (+397°C / +747°F) and receiving 43.98 S⊕ (~59,857 W/m²), HD 110014 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star HD 110014 is classified as an orange K-type star of spectral type K2 III with an effective photospheric temperature of 4,445 K, a radius of 20.9 R☉, a mass of 2.17 M☉, an estimated bolometric luminosity of 152.992 L☉. Stellar evolution modeling indicates an estimated stellar age of 0.95 Gyr and a metallicity of [Fe/H] = 0.19 dex (metal-rich relative to the Sun). From Earth, HD 110014 shines at apparent V-band magnitude 4.646 (visible to the unaided human eye under dark skies) 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).
