Kepler-1488 c
Astrophysical Synthesis & Habitability Characterization
Kepler-1488 c is a confirmed super-earth exoplanet orbiting the star Kepler-1488, located approximately 2954.4 light-years (905.83 parsecs) from the Solar System. First announced in 2021 by Kepler using the Transit detection technique (producing an estimated primary transit depth of 0.0099% across the stellar disk), this world measures 1.652 Earth radii and has a measured mass of 3.37 Earth masses. Combining its mass and radius yields a mean bulk density of 4.12 g/cm³ (a terrestrial silicate-iron composition comparable to Earth (5.51 g/cm³)), a surface gravity of 1.23 g⊕ (12.06 m/s²), and an escape velocity of 16 km/s.
In its orbital architecture around Kepler-1488, Kepler-1488 c completes one full revolution every 6.158 Earth days at a semi-major axis of 0.06959 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 122.9 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 1212 K (+939°C / +1722°F) and receiving 760.60 S⊕ (~1,035,177 W/m²), Kepler-1488 c orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star Kepler-1488 is classified as a stellar host with an effective photospheric temperature of 5,710 K, a radius of 1.524 R☉, a mass of 1.003 M☉, an estimated bolometric luminosity of 2.215 L☉. Stellar evolution modeling indicates an estimated stellar age of 5.75 Gyr and a metallicity of [Fe/H] = 0 dex (near-solar heavy-element abundance). From Earth, Kepler-1488 shines at apparent V-band magnitude 13.146 (faint and requiring research-grade or CCD telescopic photometry) in the Northern celestial hemisphere. The Kepler-1488 system is a multi-planet architecture hosting 2 confirmed worlds, with Kepler-1488 c sharing its stellar neighborhood alongside Kepler-1488 b.
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).
