List of exoplanets discovered in 2017

List of exoplanets

Note that bf means Binary flag: 0 = no known stellar binary companion; 1 = P-type binary (circumbinary); 2 = S-type binary. For exoplanets detected only by radial velocity, the mass value is actually a lower limit. (See Minimum mass for more information)
