OGLE-2016-BLG-1190L b
Astrophysical Synthesis & Habitability Characterization
OGLE-2016-BLG-1190L b is a confirmed gas giant exoplanet orbiting the star OGLE-2016-BLG-1190L, located approximately 22080.8 light-years (6770 parsecs) from the Solar System. First announced in 2017 by OGLE using the Microlensing detection technique (detected via relativistic gravitational lensing of a background source star), this world measures 12.3 Earth radii (1.1 Jupiter radii) and has a measured mass of 4253 Earth masses (13.38 Jupiter masses). Combining its mass and radius yields a mean bulk density of 12.6 g/cm³ (an iron-enriched, high-compression rocky core), a surface gravity of 28.11 g⊕ (275.66 m/s²), and an escape velocity of 208 km/s.
In its orbital architecture around OGLE-2016-BLG-1190L, OGLE-2016-BLG-1190L b completes one full revolution every 1220 Earth days (3.34Julian years) at a semi-major axis of 2.17 AU (corresponding to the middle-system regime between Mars at 1.52 AU and Jupiter at 5.20 AU). Its mean orbital velocity is approximately 19.4 km/s (compared to Earth's 29.8 km/s). The planet follows a highly eccentric trajectory (e = 0.42, swinging from 1.2586 AU at periapsis out to 3.0814 AU at apoapsis), pointing to past dynamical scattering or secular gravitational perturbations.
☁️ Atmospheric Regime (Volatile / Gas Envelope): With a radius of 12.300 R⊕, OGLE-2016-BLG-1190L 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 OGLE-2016-BLG-1190L is classified as a stellar host with a mass of 0.88 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).
