WASP-7 and Its Jupiter-Like Planet
WASP-7 is a star 529 light-years away with a mass of 1.29 solar masses, a radius of 1.47 solar radii, and a temperature of 6400 K. It is 2.5 billion years old. One planet orbits this host.
That planet is WASP-7 b, a Jupiter-like world discovered by transit in 2008. Its radius of 14.9 Earth radii exceeds Jupiter-like status by far, and its mass of 305 Earth masses sits near Jupiter's. It completes an orbit every 4.95 days, so its year lasts under five days.
The star's reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's. WASP-7 b's mean density is 0.507 g/cm³, 0.0921 times Earth's.
