HD 148427 and Its Planet
HD 148427 is a K0 III–IV star 233 light-years away with one known planet. It is 2.5 billion years old and has a mass of 1.45 solar masses and a radius of 3.22 solar radii; its temperature is 5050 K. The star's reported mass and radius estimates are larger than the Sun's, and its reported temperature is cooler than the Sun's.
HD 148427 b was discovered in 2009 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. The planet has a mass of 381 Earth masses, larger than Earth's, and an orbital period of 332 days.
