HD 131496 and Its Planet
HD 131496 is a K0 star 430 light-years away. It is 2.7 billion years old, with a mass of 1.61 solar masses and a radius of 4.3 solar radii. Its temperature is 4930 K, cooler than the Sun's, though its mass and radius estimates are larger than the Sun's. One planet is known to orbit this star.
HD 131496 b was discovered in 2011 by the radial velocity method, which detects the wobble a planet's gravity induces in its star. The planet has a minimum mass of 572 Earth masses, roughly 1.8 times Jupiter's mass. Its orbital period is 896 days.
