OGLE-2019-BLG-0468L c
Astrophysical Synthesis & Habitability Characterization
OGLE-2019-BLG-0468L c is a confirmed gas giant exoplanet orbiting the star OGLE-2019-BLG-0468L, located approximately 14350.9 light-years (4400 parsecs) from the Solar System. First announced in 2022 by OGLE using the Microlensing detection technique (detected via relativistic gravitational lensing of a background source star), this world measures 12.5 Earth radii (1.12 Jupiter radii) and has a measured mass of 3248.206 Earth masses (10.22 Jupiter masses). Combining its mass and radius yields a mean bulk density of 9.17 g/cm³ (an iron-enriched, high-compression rocky core), a surface gravity of 20.79 g⊕ (203.88 m/s²), and an escape velocity of 180.3 km/s.
☁️ Atmospheric Regime (Volatile / Gas Envelope): With a radius of 12.500 R⊕, OGLE-2019-BLG-0468L 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-2019-BLG-0468L is classified as a solar-type yellow star of spectral type G with a mass of 0.92 M☉. The OGLE-2019-BLG-0468L system is a multi-planet architecture hosting 2 confirmed worlds, with OGLE-2019-BLG-0468L c sharing its stellar neighborhood alongside OGLE-2019-BLG-0468L 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).
