HAT-P-38 and Its Jupiter-Like Planet
HAT-P-38 is a G-type star 832 light-years away, with a reported mass of 0.886 solar masses and a radius of 0.923 solar radii. Its reported temperature is 5330 K. One planet orbits this host.
That planet, HAT-P-38 b, is Jupiter-like. It was discovered by transit in 2012. It has a mass of 84.9 Earth masses, a radius of 9.25 Earth radii, and an orbital period of 4.64 days, the time it takes to complete one orbit. Its mean density is 0.591 g/cm³, 0.107 times Earth's. The star's reported mass estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's.
