Kepler-1095 b
Astrophysical Synthesis & Habitability Characterization
Kepler-1095 b is a confirmed terrestrial exoplanet orbiting the star Kepler-1095, located approximately 2584.9 light-years (792.52 parsecs) from the Solar System. First announced in 2016 by Kepler using the Transit detection technique (producing an estimated primary transit depth of 0.0145% across the stellar disk), this world measures 1.21 Earth radii and has a measured mass of 1.92 Earth masses. Combining its mass and radius yields a mean bulk density of 5.98 g/cm³ (a terrestrial silicate-iron composition comparable to Earth (5.51 g/cm³)), a surface gravity of 1.31 g⊕ (12.85 m/s²), and an escape velocity of 14.1 km/s.
In its orbital architecture around Kepler-1095, Kepler-1095 b completes one full revolution every 4.271 Earth days at a semi-major axis of 0.0514 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 130.9 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 1108 K (+835°C / +1535°F) and receiving 356.54 S⊕ (~485,251 W/m²), Kepler-1095 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star Kepler-1095 is classified as a stellar host with an effective photospheric temperature of 5,658 K, a radius of 0.92 R☉, a mass of 0.94 M☉, an estimated bolometric luminosity of 0.778 L☉. Stellar evolution modeling indicates an estimated stellar age of 4.47 Gyr and a metallicity of [Fe/H] = -0.09 dex (near-solar heavy-element abundance). From Earth, Kepler-1095 shines at apparent V-band magnitude 14.597 (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).
