The planet was detected by the radial velocity method, using the HIRES spectrometer at Keck Observatory.[21]{{OrbitboxPlanet begin | table_ref = [22] }}{{OrbitboxPlanet | exoplanet = b | mass = {{val|0.081|0.02|p=≥}} | semimajor = {{val|0.1214|0.0068}} | period = {{val|14.479|0.01}} | eccentricity = {{val|0.049|0.087}} }}{{Orbitbox end}} See also
