HD 4308 and Its Planet
HD 4308 is a G-type main-sequence star 71.8 light-years away with a single known planet, HD 4308 b. The host star is 8.68 billion years old and has a mass of 0.93 solar masses, a radius of 1.02 solar radii, and a temperature of 5700 K.
HD 4308 b was discovered in 2005 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. The planet's minimum mass is 15.9 Earth masses, larger than Earth's, and its orbital period is 15.6 days.
