OGLE-2005-BLG-169Lb explained
OGLE-2005-BLG-169Lb is an extrasolar planet located approximately 2700lk=onNaNlk=on 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, the planet has a mass of 13 times that of Earth . 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]
