KMT-2021-BLG-0909L b: A Microlensing Planet in the Galactic Bulge

KMT-2021-BLG-0909L is a star 21100 light-years away with a reported mass estimate of 0.38 solar masses, smaller than the Sun's. One planet orbits this host.

That planet, KMT-2021-BLG-0909L b, was discovered in 2023 by microlensing, a method that reveals a planet through the gravitational brightening of a background star. Its reported mass estimate is 400 Earth masses, larger than Earth's. No orbital period is reported for KMT-2021-BLG-0909L b.
