KMT-2021-BLG-1303L is a star 20500 light-years away with a mass estimate of 0.57 solar masses, which is smaller than the Sun's. That measurement describes the host star, and one planet orbits it.
The planet, KMT-2021-BLG-1303L b, was discovered in 2022 using microlensing, a technique that spots a planet through the way its gravity briefly brightens a background star. Its mass estimate is 121 Earth masses, which is larger than Earth's. A mass estimate is an approximate value rather than an exact one. No orbital period is reported for the planet.
