WASP-17: A Planet Orbiting an F-Type Star
WASP-17 is a star 1320 light-years away with a spectral type of F4. Its reported mass estimate is 1.35 solar masses, its radius estimate is 1.57 solar radii, and its temperature is 6550 K. The star's reported mass estimate is larger than the Sun's, its reported radius estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet orbits this star.
That planet, WASP-17 b, is a Jupiter-like world discovered by transit in 2009. It has a mass of 248 Earth masses and a radius of 21 Earth radii. WASP-17 b's reported mass estimate is larger than Earth's, and its reported radius estimate is larger than Earth's. Its orbital period is 3.74 days, and its mean density is 0.148 g/cm³, 0.0269 times Earth's.
