HAT-P-14b is an extrasolar planet located approximately 250 parsecs (820 ly)[1] away in the constellation of Hercules, orbiting the 10th magnitude F-type star HAT-P-14. This planet was discovered in 2010 by the HATNet Project using the transit method.[2] It was independently detected by the SuperWASP project.[3]
Orbit
HAT-P-14b is located very close orbit to its star, taking only 4.6 days to complete one orbit. Observations of the Rossiter–McLaughlin effect with the Keck telescope show that it orbits in a retrograde fashion relative to the rotation axes of its parent star.[4]
