Kepler-795 b
Astrophysical Synthesis & Habitability Characterization
Kepler-795 b is a confirmed super-earth exoplanet orbiting the star Kepler-795, located approximately 1605.1 light-years (492.12 parsecs) from the Solar System. First announced in 2016 by Kepler using the Transit detection technique (producing an estimated primary transit depth of 0.0257% across the stellar disk), this world measures 1.68 Earth radii and has a measured mass of 3.46 Earth masses. Combining its mass and radius yields a mean bulk density of 4.02 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 16.1 km/s.
In its orbital architecture around Kepler-795, Kepler-795 b completes one full revolution every 29.619 Earth days at a semi-major axis of 0.1803 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 66.2 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 580 K (+307°C / +585°F) and receiving 28.90 S⊕ (~39,333 W/m²), Kepler-795 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star Kepler-795 is classified as a stellar host with an effective photospheric temperature of 5,631 K, a radius of 0.96 R☉, a mass of 0.94 M☉, an estimated bolometric luminosity of 0.831 L☉. Stellar evolution modeling indicates an estimated stellar age of 6.46 Gyr and a metallicity of [Fe/H] = -0.02 dex (near-solar heavy-element abundance). From Earth, Kepler-795 shines at apparent V-band magnitude 13.423 (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).
