HAT-P-52 and Its Jupiter-Like Planet
HAT-P-52 is a K1 star located 1180 light-years away. Its reported mass is 0.887 solar masses, its radius is 0.893 solar radii, its temperature is 5130 K, and its age is 9.4 billion years. The star's mass and radius estimates are smaller than the Sun's, and its temperature is cooler than the Sun's. One planet is known to orbit this host.
That planet, HAT-P-52 b, is Jupiter-like. It was discovered in 2015 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Its orbital period is 2.75 days. Its radius is 11.3 Earth radii, larger than Earth's, and its mass is 260 Earth masses, also larger than Earth's. Its mean density is 0.99 g/cm³, 0.18 times Earth's.
