WASP-17
An extrasolar planet known as WASP-17b was confirmed orbiting the star as of 2009. The star is unusual for the reason that WASP-17b is believed to orbit in the opposite direction to the direction the star spins and is said to be twice the size of Jupiter, but half its mass. It is subject to deep photo-evaporation, and may be completely destroyed within 1 billion years from now.
