Delta Vega was a class M planet located in the Vulcan system, its orbit around its star brought it close enough to the planet Vulcan that the Vulcan homeworld could be seen from the surface of Delta Vega. The planet featured an icy terrain, and was home to at least two native predatory species: the hengrauggi and the drakoulias. The planet was also the location of a largely automated Starfleet outpost. (TOS movie & novelization: Star Trek; TOS comic: "Nero, Number Four")
