HD 6718 and Its Planet
HD 6718 is a G0 star 167 light-years away. Its spectral type places it in the same broad temperature class as the Sun, though its reported temperature of 5750 K is cooler than the Sun's. The star's reported mass estimate is 0.96 solar masses, smaller than the Sun's, and its radius is 1.02 solar radii. One planet is known to orbit this host.
That planet, HD 6718 b, was discovered in 2009 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. HD 6718 b completes one orbit in 2480 days. Its reported mass estimate is 763 Earth masses, larger than Earth's, and roughly 2.4 times Jupiter's mass.
