HD 8574 and Its Planet
HD 8574 is a star 146 light-years away with one known planet. Its spectral type is F8, and its reported mass estimate is 1.12 solar masses, larger than the Sun's. The star's reported radius estimate is 1.41 solar radii, also larger than the Sun's, and its temperature is 6030 K, hotter than the Sun's.
The planet HD 8574 b was discovered in 2002 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 645 Earth masses, a lower bound on its true mass, and is larger than Earth's and roughly 2.03 times Jupiter's mass. HD 8574 b completes an orbit in 227 days.
