HD 49674 and Its Lone Planet
HD 49674 is a G0 star 140 light-years away with one known planet. The star's reported temperature is cooler than the Sun's. Its mass is 0.99 solar masses and its radius is 1.04 solar radii.
The single planet, HD 49674 b, was discovered in 2002 by radial velocity. The radial velocity method measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. HD 49674 b's minimum mass is 31.8 Earth masses, a lower bound on the planet's true mass. It orbits in 4.95 days, and its minimum mass is larger than Earth's.
