Kepler-962 b

Astrophysical Synthesis & Habitability Characterization

Kepler-962 b is a confirmed super-earth exoplanet orbiting the star Kepler-962, located approximately 1342.1 light-years (411.49 parsecs) from the Solar System. First announced in 2016 by Kepler using the Transit detection technique (producing an estimated primary transit depth of 0.0441% across the stellar disk), this world measures 1.97 Earth radii and has a measured mass of 4.54 Earth masses. Combining its mass and radius yields a mean bulk density of 3.27 g/cm³ (an intermediate density indicative of a deep water-ice mantle or dense volatile envelope), a surface gravity of 1.17 g⊕ (11.47 m/s²), and an escape velocity of 17 km/s.

In its orbital architecture around Kepler-962, Kepler-962 b completes one full revolution every 12.057 Earth days at a semi-major axis of 0.09874 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 89.1 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 689 K (+416°C / +781°F) and receiving 53.82 S⊕ (~73,253 W/m²), Kepler-962 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.

The host star Kepler-962 is classified as a stellar host with an effective photospheric temperature of 5,478 K, a radius of 0.86 R☉, a mass of 0.93 M☉, an estimated bolometric luminosity of 0.598 L☉. Stellar evolution modeling indicates an estimated stellar age of 2.4 Gyr and a metallicity of [Fe/H] = 0.01 dex (near-solar heavy-element abundance). From Earth, Kepler-962 shines at apparent V-band magnitude 13.68 (faint and requiring research-grade or CCD telescopic photometry) in the Northern celestial hemisphere.
