Its apparent magnitude is 7.9 (a binocular object) and the absolute magnitude is 3.9.[3] Planetary systemHD 149143 b was discovered by the N2K Consortium, during there search for short-period gas giant planets around metal-rich stars.[3] The planet was independently discovered by the Elodie metallicity-biased search for transiting Hot Jupiters.{{OrbitboxPlanet begin| table_ref = [15] }}{{OrbitboxPlanet | exoplanet = b | mass = {{val|1.33|0.15|p=≥}} | semimajor = {{val|0.053|0.0029}} | period = {{val|4.07182|0.00001}} | eccentricity = {{val|0.0167|0.004}} }}{{Orbitbox end}} See also
