EPIC 201595106 b
Astrophysical Synthesis & Habitability Characterization
EPIC 201595106 b is a confirmed super-earth exoplanet orbiting the star EPIC 201595106, located approximately 757 light-years (232.1 parsecs) from the Solar System. First announced in 2021 by K2 using the Transit detection technique (producing an estimated primary transit depth of 0.0214% across the stellar disk), this world measures 1.565 Earth radii and has a measured mass of 7.67 Earth masses. Combining its mass and radius yields a mean bulk density of 11.03 g/cm³ (an iron-enriched, high-compression rocky core), a surface gravity of 3.13 g⊕ (30.69 m/s²), and an escape velocity of 24.8 km/s.
In its orbital architecture around EPIC 201595106, EPIC 201595106 b completes one full revolution every 0.877 Earth days at a semi-major axis of 0.0177 AU (an ultra-close orbit less than one-seventh of Mercury's 0.387 AU distance from the Sun, where strong stellar tidal forces typically induce synchronous rotation). Its mean orbital velocity is approximately 219.5 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 2038 K (+1765°C / +3209°F) and receiving 2,852.00 S⊕ (~3,881,572 W/m²), EPIC 201595106 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star EPIC 201595106 is classified as a stellar host with an effective photospheric temperature of 5,679 K, a radius of 0.98 R☉, a mass of 0.958 M☉, an estimated bolometric luminosity of 0.896 L☉. Stellar evolution modeling indicates an estimated stellar age of 6 Gyr and a metallicity of [Fe/H] = 0.01 dex (near-solar heavy-element abundance). From Earth, EPIC 201595106 shines at apparent V-band magnitude 11.746 (faint and requiring research-grade or CCD telescopic photometry) in the Northern celestial hemisphere. The EPIC 201595106 system is a multi-planet architecture hosting 2 confirmed worlds, with EPIC 201595106 b sharing its stellar neighborhood alongside K2-360 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).
