HD 8673 and Its Planet
HD 8673 is a star 123 light-years from Earth with a spectral type of F5, placing it among the hotter, more massive classes of stars. Its reported mass estimate is 1.28 solar masses and its reported radius estimate is 1.5 solar radii, both larger than the Sun's. The star's reported temperature is 6390 K, hotter than the Sun's. One planet is known to orbit this host.
That planet is HD 8673 b, discovered in 2009 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its reported mass estimate is 4210 Earth masses, larger than Earth's and roughly 13.2 times Jupiter's mass. The planet completes its orbit in 1640 days.
