HD 79498 and Its Lone Known Planet
HD 79498 is a G5 star 160 light-years away. It is cooler than the Sun and slightly larger, with a reported radius of 1.05 solar radii. Its mass is 1.08 solar masses, and its age is 2.71 billion years; its temperature is 5750 K. One planet has been found in orbit around it.
That planet, HD 79498 b, was discovered in 2011 using the radial velocity method, which detects the wobble a planet's gravity induces in its star. Its minimum mass is 426 Earth masses, roughly 1.34 times Jupiter's mass and larger than Earth. It completes one orbit every 1810 days.
