OGLE-2013-BLG-0341L B b
Astrophysical Synthesis & Habitability Characterization
OGLE-2013-BLG-0341L B b is a confirmed terrestrial exoplanet orbiting the star OGLE-2013-BLG-0341L B, located approximately 2971.3 light-years (911 parsecs) from the Solar System. First announced in 2014 by OGLE using the Microlensing detection technique (detected via relativistic gravitational lensing of a background source star), this world measures 1.16 Earth radii and has a measured mass of 1.66 Earth masses. Combining its mass and radius yields a mean bulk density of 5.86 g/cm³ (a terrestrial silicate-iron composition comparable to Earth (5.51 g/cm³)), a surface gravity of 1.23 g⊕ (12.06 m/s²), and an escape velocity of 13.4 km/s.
ℹ️ Thermal & Atmospheric Regime: Current photometric and spectroscopic constraints for OGLE-2013-BLG-0341L B b place it outside the conservative habitable zone definition pending further atmospheric characterization.
The host star OGLE-2013-BLG-0341L B is classified as a stellar host with a mass of 0.1127 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).
