WASP-52 and Its Jupiter-Like Planet
WASP-52 is a K2 V star located 570 light-years away. This host has one planet. The star is 0.4 billion years old, with a mass of 0.87 solar masses, a radius of 0.79 solar radii, and a temperature of 5000 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
The planet WASP-52 b was discovered by transit in 2012. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. WASP-52 b is Jupiter-like, a size class for planets exceeding 4 times Earth's radius. It has a mass of 146 Earth masses, a radius of 14.2 Earth radii, and an orbital period of 1.75 days. Its reported mass and radius estimates are larger than Earth's, and its mean density is 0.279 g/cm³, 0.0506 times Earth's.
