Astrophysical Synthesis & Habitability Characterization

OGLE-2016-BLG-1195L b is a confirmed terrestrial exoplanet orbiting the star OGLE-2016-BLG-1195L, located approximately 12752.7 light-years (3910 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 1.11 Earth radii and has a measured mass of 1.43 Earth masses. Combining its mass and radius yields a mean bulk density of 5.77 g/cm³ (a terrestrial silicate-iron composition comparable to Earth (5.51 g/cm³)), a surface gravity of 1.16 g⊕ (11.38 m/s²), and an escape velocity of 12.7 km/s.

ℹ️ Thermal & Atmospheric Regime: Current photometric and spectroscopic constraints for OGLE-2016-BLG-1195L b place it outside the conservative habitable zone definition pending further atmospheric characterization.

The host star OGLE-2016-BLG-1195L is classified as a stellar host with a mass of 0.078 M☉.

Earth Similarity Index (ESI): 0.97 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).
