Kepler-1450 b
Astrophysical Synthesis & Habitability Characterization
Kepler-1450 b is a confirmed super-earth exoplanet orbiting the star Kepler-1450, located approximately 1649.8 light-years (505.83 parsecs) from the Solar System. First announced in 2016 by Kepler using the Transit detection technique (producing an estimated primary transit depth of 0.0532% across the stellar disk), this world measures 1.71 Earth radii and has a measured mass of 3.57 Earth masses. Combining its mass and radius yields a mean bulk density of 3.94 g/cm³ (an intermediate density indicative of a deep water-ice mantle or dense volatile envelope), a surface gravity of 1.22 g⊕ (11.96 m/s²), and an escape velocity of 16.2 km/s.
In its orbital architecture around Kepler-1450, Kepler-1450 b completes one full revolution every 54.509 Earth days at a semi-major axis of 0.2401 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 47.9 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.
✓ Classified as a Temperate Habitable Zone Candidate.
With an estimated equilibrium temperature of 308 K (+35°C / +95°F) and an incident stellar irradiance of 3.08 S⊕ (~4,189 W/m²), Kepler-1450 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-1450 is classified as a stellar host with an effective photospheric temperature of 4,524 K, a radius of 0.68 R☉, a mass of 0.71 M☉, an estimated bolometric luminosity of 0.174 L☉. Stellar evolution modeling indicates an estimated stellar age of 4.37 Gyr and a metallicity of [Fe/H] = -0.02 dex (near-solar heavy-element abundance). From Earth, Kepler-1450 shines at apparent V-band magnitude 15.923 (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).
