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.

[edit] Notes
- Density is calculated from the mass and the radius, assuming a circular disc of eclipse relative to the Earth.
