KMT-2021-BLG-1253L b: A Microlensing Planet in the Galactic Bulge
KMT-2021-BLG-1253L is a star 22100 light-years away with a reported mass of 0.21 solar masses, smaller than the Sun's. One planet is known to orbit it: KMT-2021-BLG-1253L b.
KMT-2021-BLG-1253L b was discovered in 2022 by microlensing, a method that reveals a planet through the temporary brightening of a background star as the planet and its host pass in front of it. Its reported mass is 19.1 Earth masses, larger than Earth's. No orbital period is reported for the planet.
