Barzan II

Barzan II was the inhabited second planet in its star system. This system was located in the Alpha Quadrant.

The planet possessed few, if any, natural resources and was inhospitable to most lifeforms except its indigenous Barzans, a humanoid species. The planet was governed by the Barzanian Planetary Republic.

In 2366, the Federation starship USS Enterprise (NCC-1701-D) hosted the negotiations in orbit of Barzan II for the right to control the newly-discovered Barzan wormhole. In the end, however, it became clear that the other end of the wormhole was not stable, and its possible use as a resource vanished.

According to StarTrek.com, Barzan II was not a class M planet.

It was stated by Harry Kim in the episode "False Profits" that one terminus of the Barzan wormhole was fixed in the Alpha Quadrant.
