WASP-99 and Its Jupiter-Like Planet
WASP-99 is a star 517 light-years away with a spectral type of F8. It has an age of 1.4 billion years, a mass of 1.48 solar masses, a radius of 1.76 solar radii, and a temperature of 6180 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 orbits this host: WASP-99 b, a Jupiter-like world discovered by transit in 2014. Its radius is 11.4 Earth radii, larger than Earth's, and its mass is 772 Earth masses, also larger than Earth's and roughly 2.43 times Jupiter's mass. WASP-99 b completes an orbit every 5.75 days.
