MOA-2011-BLG-291L b: A Microlensing Planet in a Distant System
MOA-2011-BLG-291L is a star located 28700 light-years away, with a reported mass estimate of 0.11 solar masses, smaller than the Sun's. It hosts one planet, MOA-2011-BLG-291L b.
MOA-2011-BLG-291L b was discovered in 2018 by microlensing, a method that detects a planet when its gravity briefly brightens a background star. The planet's reported mass estimate is 18 Earth masses, larger than Earth's. No orbital period is reported for MOA-2011-BLG-291L b.
