HD 120084 is a star with an orbiting exoplanet[2] in the northern constellation of Ursa Minor. With an apparent magnitude of 5.91,[2] it is just visible to the naked eye in suburban skies.[5] The distance to this system is 339 light years based on parallax measurements, but it is drifting closer to the Sun with a radial velocity of −9 km/s.[1]
This is an evolved G-type giant star, a yellow giant, with a stellar classification of G7III.[2] It has an effective temperature of around 4892 K, with around 1.9 times the mass, 43 times the luminosity and 8 times the radius of the Sun.[2][3]
