HD 179079 and Its Planet
HD 179079 is a G5 star 227 light-years from Earth. Its mass is 1.05 solar masses and its radius is 1.45 solar radii, both larger than the Sun's. The star's temperature of 5670 K is cooler than the Sun's, and its age is placed at 7.88 billion years. One planet orbits this star.
That planet is HD 179079 b, discovered in 2008 by the radial velocity method. Repeated wobbles in the star's motion reveal a planet and its orbital period, which here is 14.5 days. Its minimum mass, a lower bound on its true mass, is 25.7 Earth masses, making it more massive than Earth.
