OGLE-2016-BLG-0007Lb is an exoplanet located approximately 14,020 light-years or 4,300 parsecs from Earth, in the constellation Sagittarius, orbiting the star OGLE-2016-BLG-0007L, which has a mass of 0.59+0.41

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.

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.
