KMT-2021-BLG-2478L is a star 9330 light-years away with a reported mass of 0.2 solar masses. That estimate is smaller than the Sun's mass. One planet is known to orbit this host.
That planet, KMT-2021-BLG-2478L b, was discovered in 2023 by microlensing, a method in which a foreground object's gravity briefly brightens a more distant background star. Its reported mass is 286 Earth masses, larger than Earth's mass. No orbital period is reported for the planet.
