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 ~3.2 M_J, likely a rogue planet, at a distance of about 0.56 kiloparsecs (1,800 light-years) and orbited by a ~0.47 M_🜨 exomoon; or an object of ~0.11 M_☉, likely a red dwarf star, at a distance of about 7.2 kiloparsecs (23,000 light-years) in the galactic bulge, and orbited by a ~17 M_🜨 planet. The discovery team considers the latter scenario to be more likely, but the former is a better fit.^[2][3]
