OGLE-2019-BLG-0960Lb is an exoplanet that was discovered in January 2021 by gravitational microlensing. It is approximately twice the mass of Earth, making it a super-Earth. At the time of discovery, it was the lowest mass-ratio planet to be detected via microlensing; that is, the least massive planet relative to the mass of its host star. Its host star, OGLE-2019-BLG-0960L, has an mass between 0.3 and 0.6{{nbsp}}{{Solar mass|link=y}}.
