OGLE-2005-BLG-169Lb is an extrasolar planet located approximately 2,700 parsecs (8,800 light-years) away in the constellation of Sagittarius, orbiting the star OGLE-2005-BLG-169L. This planet was discovered by the OGLE project using the gravitational microlensing method. Based on a most likely mass for the host star of 0.49 solar mass ( M☉), the planet has a mass of 13 times that of Earth ( ME). Its mass and estimated temperature are close to those of Uranus. It is speculated that this planet may either be an ice giant like Uranus, or a "naked super-Earth" with a solid icy or rocky surface. [2]
