In recent history there has been much speculation to whither or not Barnard's Star has any planetary companions.  During the late 1960s, astronomer Peter van de Kamp announced the detection of possibly two planets that revolved around each other, however his claim could never be verified, and recent observations have thus far failed to locate any evidence of planetary companions around the star.  In order for an Earth-type world to have liquid water at the surface, it would have to be located very close to Barnard's Star, at only around 0.034 to 0.082 AU.  Such a world would be tidally locked to the star.
