List of exoplanets detected by microlensing

This is the list of 20 extrasolar planets detected by microlensing, sorted by projected separations. To find planets using that method, the background star is temporarily magnified by a foreground star because of the gravity that bends light. If the foreground star has a planet, the light from background star would be slightly brighter than the star with no planet. Studying the brightness difference of background star between the foreground star with planets and foreground star with no planets, then mass can be estimated. The projected separation can be determined from how much the light bended.

The most massive planet detected by microlensing is MOA-bin-1b, which masses 3.7 M_J; the least massive is MOA-2007-BLG-192Lb, which masses 0.01 M_J or 3.3 M_⊕. The widest separation between a planet and a star is MOA-bin-1b, which is 8.3 AU; the shortest separation is MOA-2007-BLG-192Lb, which is 0.66 AU.

There are 4 members of multi-planet systems.

Notes

1. The nature of the observed system is unclear. It is either a rogue planet with about 3.2 M_J masses and a 0.5 M_⊕ exomoon or a red dwarf with 18 M_⊕ planet.
