OGLE-2014-BLG-1722L c
Astrophysical Synthesis & Habitability Characterization
OGLE-2014-BLG-1722L c is a confirmed gas giant exoplanet orbiting the star OGLE-2014-BLG-1722L, located approximately 20874 light-years (6400 parsecs) from the Solar System. First announced in 2018 by OGLE using the Microlensing detection technique (detected via relativistic gravitational lensing of a background source star), this world measures 11 Earth radii (0.98 Jupiter radii) and has a measured mass of 83.7 Earth masses (0.26 Jupiter masses). Combining its mass and radius yields a mean bulk density of 0.35 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 0.69 g⊕ (6.77 m/s²), and an escape velocity of 30.9 km/s.
☁️ Atmospheric Regime (Volatile / Gas Envelope): With a radius of 11.000 R⊕, OGLE-2014-BLG-1722L c 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 OGLE-2014-BLG-1722L is classified as a stellar host with a mass of 0.4 M☉. The OGLE-2014-BLG-1722L system is a multi-planet architecture hosting 2 confirmed worlds, with OGLE-2014-BLG-1722L c sharing its stellar neighborhood alongside OGLE-2014-BLG-1722L b.
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).
