Gamma Cephei Ab is an extrasolar planet approximately 45 light-years away in the constellation of Cepheus (the King). The planet was confirmed to be in orbit around Gamma Cephei in 2002, but was first suspected to exist around 1988 (making this planet arguably the first ''true'' extrasolar planet discovered). The planet is one of those selected by the International Astronomical Union as part of their public process for giving proper names to exoplanets.〔(NameExoWorlds: An IAU Worldwide Contest to Name Exoplanets and their Host Stars ). IAU.org. 9 July 2014〕〔(NameExoWorlds ).〕 The process involves public nomination and voting for the new name, and the IAU plans to announce the new name in mid-November 2015.〔(NameExoWorlds ).〕 == Detection and discovery ==
