Kepler-1610 b
Astrophysical Synthesis & Habitability Characterization
Kepler-1610 b is a confirmed super-earth exoplanet orbiting the star Kepler-1610, located approximately 2819.1 light-years (864.33 parsecs) from the Solar System. First announced in 2016 by Kepler using the Transit detection technique (producing an estimated primary transit depth of 0.0288% across the stellar disk), this world measures 1.61 Earth radii and has a measured mass of 3.22 Earth masses. Combining its mass and radius yields a mean bulk density of 4.25 g/cm³ (a terrestrial silicate-iron composition comparable to Earth (5.51 g/cm³)), a surface gravity of 1.24 g⊕ (12.16 m/s²), and an escape velocity of 15.8 km/s.
In its orbital architecture around Kepler-1610, Kepler-1610 b completes one full revolution every 8.702 Earth days at a semi-major axis of 0.0777 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 97.1 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 750 K (+477°C / +891°F) and receiving 56.21 S⊕ (~76,505 W/m²), Kepler-1610 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star Kepler-1610 is classified as a stellar host with an effective photospheric temperature of 5,383 K, a radius of 0.87 R☉, a mass of 0.91 M☉, an estimated bolometric luminosity of 0.57 L☉. Stellar evolution modeling indicates an estimated stellar age of 4.68 Gyr and a metallicity of [Fe/H] = 0.1 dex (metal-rich relative to the Sun). From Earth, Kepler-1610 shines at apparent V-band magnitude 16.077 (faint and requiring research-grade or CCD telescopic photometry) in the Northern celestial hemisphere. The Kepler-1610 system is a multi-planet architecture hosting 2 confirmed worlds, with Kepler-1610 b sharing its stellar neighborhood alongside Kepler-1610 c.
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).
