WASP-8b is an extrasolar planet discovered (with their stars) in the SuperWASP batch -6b to -15b. On 1 April 2008, Dr. Don Pollacco of Queen’s University Belfast announced them at the RAS National Astronomy Meeting (NAM 2008).[1]
At 49 pc away, this system is the closest of the WASP-discovered systems: closer to Earth than are HD 17156 and HD 149026. It is denser than Jupiter. If it were possible to stand on its surface, one would experience a gravitational pull of approximately 4+1⁄3g, resulting in difficulty breathing and eventual brain damage.
The planet orbits retrograde.[2][3]
The equilibrium temperature is 950 K, but this oscillates due to eccentricity.[4]
