WASP-14
WASP-14 or BD+22 2716 is a star in the constellation Boötes. The SuperWASP project has observed and classified this star as a variable star, perhaps due to the eclipsing planet.
Planetary system
WASP-14b is an extrasolar planet discovered in 2008. This is one of the densest exoplanets known. Its radius best fits the model of Fortney.
