In 2367, the USS Enterprise-D was en route to the T'lli Beta system before it was ensnared by the gravitational pull of a cosmic string fragment which a group of two-dimensional beings were attempting to enter. (TNG: "The Loss")
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-D. (Star Trek Generations, okudagram)
