Tau Cygna V
Class:	H
Type:	Planet
Location:	Tau Cygna system de Laure belt
Affiliation:	Sheliak Corporate

Tau Cygna V was the fifth planet in the Tau Cygna planetary system. This system was located within the de Laure belt. This planet was a class H planet. It had an atmosphere capable of supporting humanoid life-forms. This planet was annexed from the Federation by the Sheliak Corporate in the 2255 Treaty of Armens.

In 2274, the SS Artemis crash-landed on the planet's surface. One third of the crew died of the hyperonic radiation. The survivors established a new colony. In 2366, the population reached 15,253 people, which, however, had to be evacuated, due to the Sheliak claim on the planet. (TNG: "The Ensigns of Command")
