The Microlensing Planet of KMT-2021-BLG-1547L

KMT-2021-BLG-1547L is a star 16,500 light-years away with a mass of 0.72 solar masses, meaning it is somewhat less massive than the Sun. One planet is known to orbit it.

That planet, KMT-2021-BLG-1547L b, was discovered in 2023 by microlensing, a method that reveals a planet through the temporary brightening of a background star as a foreground star and its planet pass in front of it. The planet's reported mass estimate is 467 Earth masses, which is larger than Earth's. No orbital period is reported for KMT-2021-BLG-1547L b.
