Kepler-1595 b
Astrophysical Synthesis & Habitability Characterization
Kepler-1595 b is a confirmed terrestrial exoplanet orbiting the star Kepler-1595, located approximately 2756.1 light-years (845.02 parsecs) from the Solar System. First announced in 2016 by Kepler using the Transit detection technique (producing an estimated primary transit depth of 0.0199% across the stellar disk), this world measures 1.23 Earth radii and has a measured mass of 2.04 Earth masses. Combining its mass and radius yields a mean bulk density of 6.04 g/cm³ (a terrestrial silicate-iron composition comparable to Earth (5.51 g/cm³)), a surface gravity of 1.35 g⊕ (13.24 m/s²), and an escape velocity of 14.4 km/s.
In its orbital architecture around Kepler-1595, Kepler-1595 b completes one full revolution every 4.564 Earth days at a semi-major axis of 0.051 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 121.6 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 980 K (+707°C / +1305°F) and receiving 185.57 S⊕ (~252,558 W/m²), Kepler-1595 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star Kepler-1595 is classified as a stellar host with an effective photospheric temperature of 5,203 K, a radius of 0.8 R☉, a mass of 0.84 M☉, an estimated bolometric luminosity of 0.421 L☉. Stellar evolution modeling indicates an estimated stellar age of 4.68 Gyr and a metallicity of [Fe/H] = -0.02 dex (near-solar heavy-element abundance). From Earth, Kepler-1595 shines at apparent V-band magnitude 15.508 (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).
