Kepler-1415 b
Astrophysical Synthesis & Habitability Characterization
Kepler-1415 b is a confirmed super-earth exoplanet orbiting the star Kepler-1415, located approximately 3403.6 light-years (1043.56 parsecs) from the Solar System. First announced in 2016 by Kepler using the Transit detection technique (producing an estimated primary transit depth of 0.0198% across the stellar disk), this world measures 1.29 Earth radii and has a measured mass of 2.21 Earth masses. Combining its mass and radius yields a mean bulk density of 5.68 g/cm³ (a terrestrial silicate-iron composition comparable to Earth (5.51 g/cm³)), a surface gravity of 1.33 g⊕ (13.04 m/s²), and an escape velocity of 14.6 km/s.
In its orbital architecture around Kepler-1415, Kepler-1415 b completes one full revolution every 0.636 Earth days at a semi-major axis of 0.01416 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 242.1 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 1846 K (+1573°C / +2863°F) and receiving 2,138.08 S⊕ (~2,909,926 W/m²), Kepler-1415 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star Kepler-1415 is classified as a stellar host with an effective photospheric temperature of 5,267 K, a radius of 0.84 R☉, a mass of 0.89 M☉, an estimated bolometric luminosity of 0.487 L☉. Stellar evolution modeling indicates an estimated stellar age of 4.17 Gyr and a metallicity of [Fe/H] = 0.12 dex (metal-rich relative to the Sun). From Earth, Kepler-1415 shines at apparent V-band magnitude 15.937 (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).
