The planet was discovered in April 2025 using gravitational microlensing method developed by the Korea Astronomy and Space Science Institute and the Spitzer Space Telescope. The object is a super-Earth with a mass of 1.32 M🜨 and is located 10.1 AU from its star, which is slightly further than Saturn. One year on this planet is equivalent to 39 Earth years.[2] The NASA Exoplanet Archive estimated the planet's radius at 1.09 R🜨[1]
Scientists hypothesize that OGLE-2016-BLG-0007Lb is the core of a giant planet that failed to accrete enough gas from the protoplanetary disk to become a gas giant, similar to Jupiter or Saturn.[2]
