OGLE-2006-BLG-109L (where the last 'L' stands for lens) is a dim magnitude 17 M0V galactic bulge star approximately 4,920 light-years away in the constellation of Scorpius.
In 2008, two extrasolar planets were discovered around the star using gravitational microlensing.
The two planets are at a distance from their star that make them suspected analogs of Jupiter and Saturn.
[2] Both planets were discovered simultaneously by gravitational microlensing in a common effort by the Optical Gravitational Lensing Experiment, microFUN, MOA, PLANET and RoboNet collaborations, as announced on 14 February 2008.
This is the first planetary system where more than one planet was detected using gravitational microlensing.
