Kepler-160 c
Astrophysical Synthesis & Habitability Characterization
Kepler-160 c is a confirmed sub-neptune exoplanet orbiting the star Kepler-160, located approximately 3056.1 light-years (937.01 parsecs) from the Solar System. First announced in 2014 by Kepler using the Transit detection technique (producing an estimated primary transit depth of 0.0951% across the stellar disk), this world measures 3.76 Earth radii (0.34 Jupiter radii) and has a measured mass of 13.6 Earth masses. Combining its mass and radius yields a mean bulk density of 1.41 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 0.96 g⊕ (9.41 m/s²), and an escape velocity of 21.3 km/s.
In its orbital architecture around Kepler-160, Kepler-160 c completes one full revolution every 13.699 Earth days at a semi-major axis of 0.1192 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 94.7 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 771 K (+498°C / +928°F) and receiving 84.85 S⊕ (~115,478 W/m²), Kepler-160 c orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star Kepler-160 is classified as a stellar host with an effective photospheric temperature of 5,471 K, a radius of 1.118 R☉, a mass of 1.003 M☉, an estimated bolometric luminosity of 1.005 L☉. Stellar evolution modeling indicates an estimated stellar age of 6.03 Gyr and a metallicity of [Fe/H] = 0.2 dex (metal-rich relative to the Sun). From Earth, Kepler-160 shines at apparent V-band magnitude 14.816 (faint and requiring research-grade or CCD telescopic photometry) in the Northern celestial hemisphere. The Kepler-160 system is a multi-planet architecture hosting 3 confirmed worlds, with Kepler-160 c sharing its stellar neighborhood alongside Kepler-160 b, Kepler-160 d.
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).
