Thasus
Type:	Planet
Native Species:	Thasians

Thasus was the homeworld to the non-corporeal Thasians. Sensor probes of the planet had revealed Thasus to be uninhabitable, with little or no vegetation.

In 2249, a transport crashed on Thasus, with a young boy, Charlie Evans, the only survivor. In order to keep the boy alive, the Thasians cared for him and granted him their psychokinetic abilities. In 2266, Charlie was rescued from Thasus and transferred to the starship Enterprise, which was to transport Charlie to Alpha V colony, where he would be reunited with his closest living relatives. Charlie's powers proved dangerous, however, as he used them for his own amusement without regard for the consequences to others. Realizing that Charlie was gone, the Thasians retrieved him from the Enterprise, and took him back to Thasus, where he would no longer pose a danger. (TOS: "Charlie X")
