Telsius Prime
Native Species:	Telsians
Location:	Telsius system Delta Quadrant

Telsius Prime was the main planet in the Telsius planetary system. This planet was in the Delta Quadrant and was the homeworld of the Telsians. It was located 30,342.4 light years from Earth.

A mine on Telsius was visited by con artists Dala, Mobar, and Zar in 2376. Disguised as USS Voyager officers, they cheated the miners out of ten kilotons of bolomite when the station was having a dilithium shortage. The mine's Chief of Mining Operations was Orek.

It was also the location of Telsian Security, which was known for having "persuasive methods of determining the truth". (VOY: "Live Fast and Prosper")
