This star is larger, hotter, brighter, and more massive than our Sun. Also its metal content almost twice as much as the Sun. In 2009, a gas giant planet was found in orbit around the star.{{OrbitboxPlanet begin | table_ref = }}{{OrbitboxPlanet | exoplanet = b | mass = ≥ {{val|0.85|+0.67|-0.05}} | period = {{val|1027|28}} | semimajor = {{val|2.45|+0.04|-0.05}} | eccentricity = {{val|0.52|+0.04|-0.09}} }}{{Orbitbox end}} See also
