NGC 2682 YBP 1514 b
Astrophysical Synthesis & Habitability Characterization
NGC 2682 YBP 1514 b is a confirmed gas giant exoplanet orbiting the star NGC 2682 YBP 1514, located approximately 2981.8 light-years (914.22 parsecs) from the Solar System. First announced in 2014 by Multiple Observatories using the Radial Velocity detection technique (measuring periodic Doppler reflex motion in the host star's spectrum), this world measures 14 Earth radii (1.25 Jupiter radii) and has a measured mass of 127.132 Earth masses (0.4 Jupiter masses). Combining its mass and radius yields a mean bulk density of 0.26 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 0.65 g⊕ (6.37 m/s²), and an escape velocity of 33.7 km/s.
In its orbital architecture around NGC 2682 YBP 1514, NGC 2682 YBP 1514 b completes one full revolution every 5.118 Earth days. The planet follows a highly eccentric trajectory (e = 0.28), pointing to past dynamical scattering or secular gravitational perturbations.
☁️ Atmospheric Regime (Volatile / Gas Envelope): With a radius of 14.000 R⊕, NGC 2682 YBP 1514 b exceeds the empirical ~1.8–2.2 R⊕ Fulton radius valley threshold, indicating a substantial hydrogen-helium or supercritical volatile envelope without a conventional solid terrestrial surface.
The host star NGC 2682 YBP 1514 is classified as a solar-type yellow star of spectral type G5 V with an effective photospheric temperature of 5,725 K, a radius of 0.89 R☉, a mass of 0.96 M☉, an estimated bolometric luminosity of 0.763 L☉. Stellar evolution modeling indicates an estimated stellar age of 4.15 Gyr and a metallicity of [Fe/H] = 0.03 dex (near-solar heavy-element abundance). From Earth, NGC 2682 YBP 1514 shines at apparent V-band magnitude 14.684 (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).
