OGLE-2007-BLG-368 is a faint and far away star located at least 19,200 light years away from Sun in the constellation Scorpius. This star has mass 0.65 solar masses which implies that it could probably be a late K-type star. In 2009 during the microlensing event, a Neptune-mass planet was found orbiting this star at a distance of 3.3 AU and has mass 22 times that of Earth.[1]
