HAT-P-8 and Its Jupiter-Like Planet
HAT-P-8 is a star 690 light-years away with a spectral type of F6. Its mass is 1.29 solar masses, and its radius is 1.43 solar radii. Its temperature is 6400 K. The star's reported mass estimate is larger than the Sun's, its reported radius estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's.
One planet orbits this host: HAT-P-8 b, a Jupiter-like world discovered by the transit method in 2008. Its mass is 407 Earth masses, which is larger than Earth's and roughly 1.28 times Jupiter's mass. Its radius is 15.7 Earth radii, larger than Earth's. HAT-P-8 b completes an orbit every 3.08 days. Its mean density is 0.58 g/cm³, 0.105 times Earth's.
