HAT-P-28 b: A Transiting Giant

HAT-P-28 is a star of spectral type G3 located 1310 light-years away. It has an age of 6.1 billion years, a mass of 1.02 solar masses, a radius of 1.1 solar radii, and a temperature of 5680 K. Its radius is larger than the Sun's, while its temperature is cooler than the Sun's. One planet orbits this host.

That planet, HAT-P-28 b, was discovered in 2011 by the transit method. It is classified as Jupiter-like, with a radius of 13.6 Earth radii and a mass of 199 Earth masses, both larger than Earth's. Its orbital period is 3.26 days. Its mean density is 0.437 g/cm³, 0.0794 times Earth's.
