WASP-15 and Its Jupiter-Like Planet
WASP-15 is a star 920 light-years away with a spectral type of F7. It is 2.4 billion years old, has a mass of 1.31 solar masses and a radius of 1.52 solar radii, and its temperature is 6410 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet has been found orbiting this host.
That planet, WASP-15 b, is a Jupiter-like world discovered by the transit method in 2009. Its radius is 15.8 Earth radii, larger than Earth's, and its mass is 172 Earth masses, also larger than Earth's. It completes an orbit every 3.75 days. Its mean density is 0.24 g/cm³, 0.0435 times Earth's.
