HD 101930 and Its Orbiting Planet
HD 101930 is a K0 star located 97.9 light-years away. It is cooler than the Sun, at a reported temperature of 5190 K, and its reported radius estimate is smaller than the Sun's, at 0.79 solar radii. The star has a reported upper limit of 1 billion years in age and a mass of 0.9 solar masses. One planet is known to orbit this host.
That planet, HD 101930 b, was discovered in 2005 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. It has a minimum mass of 79.5 Earth masses, larger than Earth's, and an orbital period of 70.5 days.
