List of exoplanets detected by microlensing
Wikimedia list article
This is a list of exoplanets detected by gravitational microlensing. The phenomenon results in the background star's light being warped around a foreground object, causing a distorted image. If the foreground object is a star with an orbiting planet, we would observe an abnormally bright image. By comparing the luminosity and light distortion of the background star to theoretical models, we can estimate the planet's mass and the distance from its star.
The least massive planet detected by microlensing is KMT-2020-BLG-0414Lb, which has a mass about 0.960 times the mass of earth, or OGLE-2016-BLG-0007Lb, which has a mass about 1.32 times the mass of earth. The widest separation between a planet and a star is OGLE-2008-BLG-092Lb, which is 15 AU; the shortest separation is KMT-2020-BLG-0414Lc, which is 0.12 AU. There are 9 known multi-planetary systems detected by microlensing, all of which have two planets.
List
Yellow rows denote the members of multi-planet systems. Green rows denote the members of multi-star systems.
Candidate rogue planets
A number of candidate rogue planets have been detected by microlensing.
Unconfirmed detections
Some microlensing events, such as MACHO-98-BLG-35 and PA-99-N2, suggest the possible presence of a planetary companion to the lensing star, but this is unconfirmed.
Begin with the source’s own compact description: “List of exoplanets detected by microlensing” is wikimedia list article. The dossier treats that line as a proposition to test through List, exoplanets and detected, not as a finished interpretation.
Why this record matters
The phrase “wikimedia list article” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q4437785. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2020, 2016 and 2008.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
