HAT-P-22 and Its Jupiter-like Planet
HAT-P-22 is a G5 star 267 light-years away with an age of 12.4 billion years, a mass of 0.916 solar masses, a radius of 1.04 solar radii, and a temperature of 5300 K. Its reported mass estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet has been reported in orbit around this host.
That planet, HAT-P-22 b, is a Jupiter-like world discovered by transit in 2010. Its orbital period is 3.21 days. Its mass is 785 Earth masses, which is larger than Earth's mass and roughly 2.47 times Jupiter's mass. Its radius is 12.9 Earth radii, larger than Earth's radius. Its mean density is 2.02 g/cm³, 0.367 times Earth's.
