Kepler-1480 b
Astrophysical Synthesis & Habitability Characterization
Kepler-1480 b is a confirmed super-earth exoplanet orbiting the star Kepler-1480, located approximately 1633.7 light-years (500.89 parsecs) from the Solar System. First announced in 2016 by Kepler using the Transit detection technique (producing an estimated primary transit depth of 0.0357% across the stellar disk), this world measures 1.67 Earth radii and has a measured mass of 3.43 Earth masses. Combining its mass and radius yields a mean bulk density of 4.06 g/cm³ (a terrestrial silicate-iron composition comparable to Earth (5.51 g/cm³)), a surface gravity of 1.23 g⊕ (12.06 m/s²), and an escape velocity of 16 km/s.
In its orbital architecture around Kepler-1480, Kepler-1480 b completes one full revolution every 22.127 Earth days at a semi-major axis of 0.1525 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 75 km/s (compared to Earth's 29.8 km/s). The orbit is modeled as circular (e = 0.00), maintaining a constant stellar distance throughout its year.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 721 K (+448°C / +838°F) and receiving 16.32 S⊕ (~22,207 W/m²), Kepler-1480 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star Kepler-1480 is classified as a stellar host with an effective photospheric temperature of 5,156 K, a radius of 0.81 R☉, a mass of 0.85 M☉, an estimated bolometric luminosity of 0.416 L☉. Stellar evolution modeling indicates an estimated stellar age of 4.79 Gyr and a metallicity of [Fe/H] = 0.07 dex (metal-rich relative to the Sun). From Earth, Kepler-1480 shines at apparent V-band magnitude 14.703 (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).
