MOA-2015-BLG-337L b: A Microlensing World Around a Tiny Star

MOA-2015-BLG-337L is a host star 23,200 light-years away with a reported mass of 0.0094 solar masses, an estimate smaller than the Sun's mass. One planet is known to orbit it.

That planet, MOA-2015-BLG-337L b, was discovered in 2018 by microlensing, a method that reveals a planet through the way its gravity briefly brightens a background star. Its reported mass is 33.7 Earth masses, larger than Earth's mass.

No orbital period is reported for MOA-2015-BLG-337L b, so its year remains unmeasured. The star's low mass, paired with the planet's comparatively large mass, makes this a striking system: a world of 33.7 Earth masses circling a star of only 0.0094 solar masses.
