(covers information from several alternate timelines)

The M-class inhabited world Veridian IV was the fourth of six planets in the Veridian star system. The planet had two moons, and, as of 2371, was home to a pre-industrial humanoid society with a population of 230 million. (Star Trek Generations)

In an alternate timeline in 2371, Dr. Tolian Soran's plan to collapse the Veridian sun succeeded and the entire Veridian system, including Veridian IV, was destroyed by the resultant shock wave. (Star Trek Generations)

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