This is a List of exoplanets discovered in 2013.
For exoplanets detected only by radial velocity, the mass value is actually a lower limit. (See Minimum mass for more information)
MOA-2011-BLG-262L was once considered as a candidate exoplanet. 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.
