HD 30669 and Its Planet
HD 30669 is a G-type main-sequence dwarf 189 light-years away. Its spectral type is G9 V. The star is 4.8 billion years old, has a mass of 0.92 solar masses and a radius of 0.91 solar radii, and its temperature is 5400 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet orbits this host.
HD 30669 b was discovered in 2014 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 149 Earth masses, larger than Earth's, and its orbital period is 1680 days.
