T'lli Beta

T'lli Beta was an inhabited planet in the T'lli Beta system. This was the homeworld of the T'lli Betans.

In 2367, the USS Enterprise (NCC-1701-D) was en route to T'lli Beta before it was ensnared by the gravitational pull of a cosmic string fragment which a group of two-dimensional lifeforms were attempting to enter. 

In 2371, the location of T'lli Beta was labeled in the star chart Data and Picard were studying in stellar cartography aboard the USS Enterprise (NCC-1701-D). (, okudagram)
