Gamma Cephei Ab is an extrasolar planet approximately 45 light-year away in the constellation of Cepheus (the King). The planet was confirmed to orbit Gamma Cephei in 2002, but was suspected to be a planet around 1988 (making this planet the first true extrasolar planet discovered).
The first indications of Gamma Cephei Ab were reported in July 1988. The planet was tentatively identified by a Canadian team of astronomers (lead by Bruce Campbell, Gordon Walker, and Stephenson Yang, while its existence was also announced by Anthony Lawton and P. Wright in 1989. Though not confirmed, this world would have been the first true extrasolar planet, and it was hypothesized based on the same radial velocity technique later used successfully by others. However, the claim was retracted in 1992 due to the quality of the data not being good enough to make a solid discovery.
On September 24, 2002, Gamma Cephei Ab was finally confirmed. The team of astronomers (including William D. Cochran, Artie P....
