Delta Vega I was a class M or class G geocrystalline/class F planet planet located in the Delta Vega system of the Delta Vega sector at an edge of the galaxy, near the galactic barrier, in the Alpha Quadrant. By the mid-23rd century the planet was home to the Federation's Mineral Processing Facility DSE-Grissom, an unmanned lithium cracking station. The planet remained an uninhabited industrial site until at least 2376, but by 2381 was the home to a colony.
