# The OGLE-2006-BLG-109L system

OGLE-2006-BLG-109L is a star in Scorpius, 4925 ly away, with 2 known planets. Their orbits run from 2.30 to 4.50 AU. All of them were detected by microlensing.

## The planets, innermost first

| Planet | Orbit (AU) | Period | Radius | Mass | Equilibrium T |
| --- | --- | --- | --- | --- | --- |
| [b](https://spacecatalog.org/object/ogle-2006-blg-109l-b) | 2.30 | 4.897 yr | 14.00 R⊕ | 231 M⊕ | 82 K |
| [c](https://spacecatalog.org/object/ogle-2006-blg-109l-c) | 4.50 | 13.49 yr | 11.10 R⊕ | 86 M⊕ | 59 K |

Every figure is the planet's composite parameter from the [NASA Exoplanet Archive (Planetary Systems Composite Parameters)](https://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=PSCompPars), one consistent set per world. Semi-major axes are orbits about the star, not distances from Earth.
