It orbits at .4 AU each and every 233 days and has a proposed mass of 3.2 MEarth. Therefore, it appears that Barnard's Star in fact does not host Earth-mass planets or larger, in very hot and temperate orbits, unlike other M-dwarf stars that commonly have these kinds of planets in shut-in orbits. It was considered to have a least of 3.2 MEarth (Earth masses) and orbit at .4 AU.
