KMT-2022-BLG-0440L and Its Planet

KMT-2022-BLG-0440L is a star located 11,400 light-years away, with a reported mass estimate of 0.53 solar masses. That estimate is smaller than the Sun's mass. One planet has been found orbiting this star.

That planet, KMT-2022-BLG-0440L b, was discovered in 2023 by microlensing. Its reported mass estimate is 15.4 Earth masses, which is larger than Earth's mass. Microlensing detects a planet through the way its gravity briefly brightens a background star. No orbital period is reported for KMT-2022-BLG-0440L b.
