Depiction of the Veridian system

The Veridian system was a planetary system. It consisted of the primary Veridian and six planets. It was located not far from the Amargosa star.

In an alternate timeline, Dr. Tolian Soran collapsed the Veridian sun with a trilithium device and the entire system was destroyed by a level-12 shock wave. (Star Trek Generations)

According to Star Trek: Star Charts (p. 65), the Veridian system was located in the Beta Quadrant.
