OGLE-2005-BLG-071L b
Astrophysical Synthesis & Habitability Characterization
OGLE-2005-BLG-071L b is a confirmed gas giant exoplanet orbiting the star OGLE-2005-BLG-071L, located approximately 10437 light-years (3200 parsecs) from the Solar System. First announced in 2005 by OGLE using the Microlensing detection technique (detected via relativistic gravitational lensing of a background source star), this world measures 13 Earth radii (1.16 Jupiter radii) and has a measured mass of 1200 Earth masses (3.78 Jupiter masses). Combining its mass and radius yields a mean bulk density of 3.01 g/cm³ (an intermediate density indicative of a deep water-ice mantle or dense volatile envelope), a surface gravity of 7.1 g⊕ (69.63 m/s²), and an escape velocity of 107.5 km/s.
❄️ Thermal Regime (Cryogenic Zone): With an equilibrium temperature of 55 K (-218°C / -360°F), surface water and volatile species on OGLE-2005-BLG-071L b would remain locked in cryogenic ice phases unless warmed by subsurface tidal or radiogenic heating.
The host star OGLE-2005-BLG-071L is classified as a stellar host with a mass of 0.46 M☉.
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).
