HD 109749 and Its Planet
HD 109749 is a G3 V star 206 light-years away. This Sun-like star has a reported mass of 1.2 solar masses, a radius of 1.24 solar radii, and a temperature of 5900 K. It is 3.7 billion years old. One planet is known to orbit it.
That planet, HD 109749 b, was discovered in 2005 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 85.8 Earth masses, a lower bound on its true mass, and it completes an orbit every 5.24 days.
