Gamma Alpha V

Gamma Alpha V was a Class M planet in the Alpha or Beta Quadrant of the Milky Way Galaxy.

It was explored by a robotic probe roughly ten years prior to 2264. The probe found the planet to be Class M, but with no inhabitants. 

The planet was colonized by Alexander Lazarus and a number of Androids he had built, which had all been imbued with the thoughts and memories of a significant figure from Earth's history. 

In 2264, on Stardate 10:26.3, the USS Enterprise explored the planet, meeting George Washington among others, before Spock was kidnapped by Lazarus, who wanted to use his brain to create a new series of androids based on Vulcan history. The ensuing conflict lead to the destruction of the planet, in an explosion whose shockwaves shook the escaping Enterprise.
