Astrophysical Synthesis & Habitability Characterization

Kepler-1472 b is a confirmed super-earth exoplanet orbiting the star Kepler-1472, located approximately 4824.3 light-years (1479.14 parsecs) from the Solar System. First announced in 2016 by Kepler using the Transit detection technique (producing an estimated primary transit depth of 0.0194% across the stellar disk), this world measures 1.9 Earth radii and has a measured mass of 4.27 Earth masses. Combining its mass and radius yields a mean bulk density of 3.43 g/cm³ (an intermediate density indicative of a deep water-ice mantle or dense volatile envelope), a surface gravity of 1.18 g⊕ (11.57 m/s²), and an escape velocity of 16.8 km/s.

In its orbital architecture around Kepler-1472, Kepler-1472 b completes one full revolution every 38.131 Earth days at a semi-major axis of 0.2322 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 66.2 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.

⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 613 K (+340°C / +644°F) and receiving 57.08 S⊕ (~77,685 W/m²), Kepler-1472 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.

The host star Kepler-1472 is classified as a stellar host with an effective photospheric temperature of 6,159 K, a radius of 1.25 R☉, a mass of 1.16 M☉, an estimated bolometric luminosity of 2.017 L☉. Stellar evolution modeling indicates an estimated stellar age of 3.09 Gyr and a metallicity of [Fe/H] = 0.03 dex (near-solar heavy-element abundance). From Earth, Kepler-1472 shines at apparent V-band magnitude 14.666 (faint and requiring research-grade or CCD telescopic photometry) in the Northern celestial hemisphere.
