Astrophysical Synthesis & Habitability Characterization

Gaia22dkvL b is a confirmed gas giant exoplanet orbiting the star Gaia22dkvL, located approximately 4142.2 light-years (1270 parsecs) from the Solar System. First announced in 2024 by European Space Agency (ESA) Gaia Satellite using the Microlensing detection technique (detected via relativistic gravitational lensing of a background source star), this world measures 14.1 Earth radii (1.26 Jupiter radii) and has a measured mass of 187.837 Earth masses (0.59 Jupiter masses). Combining its mass and radius yields a mean bulk density of 0.37 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 0.94 g⊕ (9.22 m/s²), and an escape velocity of 40.8 km/s.

☁️ Atmospheric Regime (Volatile / Gas Envelope): With a radius of 14.100 R⊕, Gaia22dkvL 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 Gaia22dkvL is classified as a stellar host with a mass of 1.145 M☉.

Earth Similarity Index (ESI): 0.27 Earth Baseline = 1.00
0.00 Dissimilar 0.50 Mars Scale 0.70 Analog Regime 1.00 Earth

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).
