Malon Prime was the main planet in the Malon planetary system, in the Delta Quadrant. This planet was the homeworld of the Malon species. It was said to be one of the most beautiful planets in the quadrant, despite the fact that Malon industry produced massive quantities of antimatter waste. This was made possible by waste export vessels, that transported the hazardous waste far from Malon home space. (VOY: "Juggernaut")
