MOA-2011-BLG-262L is a red dwarf with an orbiting exoplanet, both detected through the gravitational microlensing event MOA-2011-BLG-262. It was once believed to be either an exoplanet with 3.2 times the mass of Jupiter and a exomoon with 0.47 times Earth's mass or a red dwarf with a mass of 0.11 solar masses orbited by a planet, but the latter scenario was confirmed in 2024 based on observations of the host star by the Keck telescope, 10 years after the ending of the microlensing event.
The system is located from Earth, in the constellation Sagittarius. The host star is a red dwarf, with 19% the Sun's mass and a faint apparent magnitude of 22.3 in the K-band. It has a transverse velocity of, the highest ever found for any star with a known exoplanet.
