Kepler-1652 b
Astrophysical Synthesis & Habitability Characterization
Kepler-1652 b is a confirmed super-earth exoplanet orbiting the star Kepler-1652, located approximately 821.9 light-years (252 parsecs) from the Solar System. First announced in 2017 by Kepler using the Transit detection technique (producing an estimated primary transit depth of 0.1475% across the stellar disk), this world measures 1.6 Earth radii and has a measured mass of 3.19 Earth masses. Combining its mass and radius yields a mean bulk density of 4.29 g/cm³ (a terrestrial silicate-iron composition comparable to Earth (5.51 g/cm³)), a surface gravity of 1.25 g⊕ (12.26 m/s²), and an escape velocity of 15.8 km/s.
In its orbital architecture around Kepler-1652, Kepler-1652 b completes one full revolution every 38.097 Earth days at a semi-major axis of 0.1654 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 47.2 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.
✓ Classified as a Temperate Habitable Zone Candidate.
With an estimated equilibrium temperature of 268 K (-5°C / +23°F) and an incident stellar irradiance of 0.81 S⊕ (~1,102 W/m²), Kepler-1652 b orbits within the empirical circumstellar habitable zone where a rocky surface under sufficient atmospheric pressure can maintain liquid surface water.
The host star Kepler-1652 is classified as a stellar host with an effective photospheric temperature of 3,638 K, a radius of 0.382 R☉, a mass of 0.404 M☉, an estimated bolometric luminosity of 0.023 L☉. Stellar evolution modeling indicates an estimated stellar age of 3.2 Gyr and a metallicity of [Fe/H] = -0.3 dex (metal-poor relative to the Sun). From Earth, Kepler-1652 shines at apparent V-band magnitude 16.86 (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).
