OGLE-2005-BLG-071L is a distant, magnitude 19.5 galactic bulge star located in the constellation Scorpius, approximately 11,000 light years away from the Solar System. The star is probably a red dwarf with a mass 43% of that of the Sun.

Planetary system

In 2005 an exoplanet was discovered orbiting this star by the microlensing method,[3] the second planet found by this method.[2] The planet was later confirmed by the Keck telescope and its properties were refined.[2]
