Zeta Major


 * ''You may be looking for the novel of the same name

Zeta Major was, according to Lord Ferdinand du Vindice, a "trapped asteroid". Tegan discovered documents of the Zeta Project which described it as, "The outer planet in the Zeta System. A captured asteroid."

It was also headquarters for the Zeta Project and, according to documents found by Ferdinand "engineered as an experimental complex to facilitate conversion". Ferdinand therefore saw it as a legitimate military target and all but destroyed it, with Nyssa and Tegan in tow. (PDA: Zeta Major)
