Vesper

Vesper is a star system located in the contested space between the Federation and the Klingon Empire, in the galaxy's Beta Quadrant. Vesper II is home to an unaligned Human colony. 

Details
The Vesper system was located in the Mempa sector of the Pi Canis sector block. Its second planet was colonized by Humans in 2327. By 2409, the planet's population numbered 6.7 million. 

History
After the Dominion War, the Vesper government considered applying for Federation membership but put these plans on indefinite hold when the Federation and Klingon Empire went to war.

In 2409, Starfleet sent a ship to check anomalous readings detected on asteroids near Vesper II. The Vulcan Science Academy theorized these readings may infer a new element. The asteroid field served as a well-known base to Nausicaan raiders. Starfleet dispatched the Nausicaan vessels but found no new elements on the asteroids. However, the readings were still of interest to the Starfleet Corps of Engineers.
