OGLE-2016-BLG-0007L b
Astrophysical Synthesis & Habitability Characterization
OGLE-2016-BLG-0007L b is a confirmed terrestrial exoplanet orbiting the star OGLE-2016-BLG-0007L, located approximately 14024.7 light-years (4300 parsecs) from the Solar System. First announced in 2025 by OGLE using the Microlensing detection technique (detected via relativistic gravitational lensing of a background source star), this world measures 1.09 Earth radii and has a measured mass of 1.32 Earth masses. Combining its mass and radius yields a mean bulk density of 5.62 g/cm³ (a terrestrial silicate-iron composition comparable to Earth (5.51 g/cm³)), a surface gravity of 1.11 g⊕ (10.89 m/s²), and an escape velocity of 12.3 km/s.
In its orbital architecture around OGLE-2016-BLG-0007L, OGLE-2016-BLG-0007L b completes one full revolution every 14200 Earth days (38.88Julian years) at a semi-major axis of 10.1 AU (a wide outer-system orbit beyond Jupiter's 5.20 AU distance in our Solar System). Its mean orbital velocity is approximately 7.7 km/s (compared to Earth's 29.8 km/s).
ℹ️ Thermal & Atmospheric Regime: Current photometric and spectroscopic constraints for OGLE-2016-BLG-0007L b place it outside the conservative habitable zone definition pending further atmospheric characterization.
The host star OGLE-2016-BLG-0007L is classified as a stellar host with a mass of 0.59 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).
