HD 10647 and Its Planet
HD 10647 is a star 56.5 light-years away with a single known planet, HD 10647 b. The host is an F9 V star, a main-sequence dwarf hotter and more massive than the Sun. It has an age of 1.4 billion years, a mass of 1.11 solar masses, a radius of 1.1 solar radii, and a temperature of 6220 K. Its reported mass and radius are both larger than the Sun's, and its reported temperature is hotter than the Sun's.
HD 10647 b was discovered in 2006 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 has a minimum mass of 299 Earth masses, a lower bound on its true mass, and an orbital period of 989 days. Its minimum mass is larger than Earth's.
