WASP-32 and Its Jupiter-Like Planet
WASP-32 is a star 900 light-years away with a mass of 1.3 solar masses, a radius of 1.03 solar radii, and a temperature of 6430 K. Its reported mass estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet orbits this host.
That planet is WASP-32 b, a Jupiter-like world discovered by transit in 2010. Transit describes a planet passing in front of its star from our viewpoint and causing a small dip in observed brightness; repeated dips help establish orbital periods. WASP-32 b completes an orbit every 2.72 days. Its radius of 10.8 Earth radii is larger than Earth's, and its mass of 836 Earth masses is also larger than Earth's, roughly 2.63 times Jupiter's mass. Its mean density is 3.7 g/cm³, 0.671 times Earth's.
