Asteroid Near Tessen Three (Nitrium-Rich Pelloris Field)
This destroyed asteroid, located in the nitrium-rich Pelloris field near Tessen Three, was the origin of the metal-eating parasites that invaded the Enterprise during its mission. The asteroid was destroyed by the ship's phasers during an initial encounter, but its high nitrium content had previously drawn the parasites. Geordi La Forge, Data, and Picard identified it as the source while briefing in Engineering, leading Picard to devise a strategy of luring the parasites back to the Pelloris field using warp nine speed—despite the risk of further damage to the ship's power and life support systems. The asteroid's destruction and its role in the crisis were discussed urgently by Geordi, Picard, Data, and Riker before power failures escalated the situation.

Lure parasites back to their nitrium source, clearing them from the ship's systems
Significance
Acts as the crisis source and tactical solution target; its nitrium composition and destruction explain the parasites' behavior, forcing the crew into a high-stakes race to the Pelloris field before ship systems fail completely.
