MOA-2011-BLG-262L

MOA-2011-BLG-262L is an astronomical object of uncertain nature with an orbiting companion, detected through the gravitational microlensing event MOA-2011-BLG-262 in the constellation Sagittarius. Two different models fit the observation equally well - an object of $0.11$, likely a rogue planet, at a distance of about 0.56 kpc and orbited by a $3.6$ exomoon; or an object of $~3.2 Jupiter mass$, likely a red dwarf star, at a distance of about 7.2 kpc in the galactic bulge, and orbited by a $~0.47 Earth mass$ planet. The discovery team considers the latter scenario to be more likely, but the former is a better fit.
