Description: WASP-11b/HAT-P-10b or WASP-11Ab/HAT-P-10Ab is an extrasolar planet discovered in 2008. The discovery was announced by press release by the SuperWASP project in April 2008 along with planets WASP-6b through to WASP-15b, however at this stage more data was needed to confirm the parameters of the planets and the coordinates were not given. On 26 September 2008, the HATNet Project's paper describing the planet which they designated HAT-P-10b appeared on the arXiv preprint server. The SuperWASP team's paper appeared as a preprint on the Extrasolar Planets Encyclopaedia on the same day, confirming that the two objects were in fact the same, and the teams agreed to use the combined designation.
