HD 120084
HD 120084 is a star in the constellation of Ursa Minor. With an apparent magnitude of 5.91, it is just visible to the naked eye in suburban skies.
It is a yellow giant of spectral type G7III and surface temperature of around 4892 K, around 2.4 times the mass, 43 times the luminosity and 9 times the radius of our Sun. A planet with 4.5 times the mass of Jupiter and a highly eccentric orbit (with an eccentricity of 0.66) was discovered by precisely measuring the radial velocity
years old, it has cooled and expanded since it was an A-type main sequence star. Around 390 light-years distant, it shines with an apparent magnitude of 5.04. A planet around 11 times the mass of Jupiter was discovered orbiting the star with a period of 516 days in 2009. HD 120084 is another evolved star, this time a yellow giant of spectral type G7III, around 2.4 times the mass of the Sun. It has a planet 4.5 times the mass of Jupiter with one of the most eccentric
