HATS-28 and Its Giant Planet
HATS-28 is a G-type star located 1750 light-years away, with a reported mass of 0.929 solar masses and a radius of 0.922 solar radii. Its reported temperature is 5500 K, and it is estimated to be 6.2 billion years old. One planet is known to orbit this star.
That planet, HATS-28 b, is a Jupiter-like world discovered by the transit method in 2016. It completes an orbit in 3.18 days. Its radius is 13.4 Earth radii, larger than Earth's, and its mass is 214 Earth masses, also larger than Earth's. The planet's mean density is 0.491 g/cm³, which is 0.0891 times Earth's. The star's reported mass and radius estimates are both smaller than the Sun's.
