Nelvana II was the uninhabited second planet of the Nelvana system. This Beta Quadrant system was located in the Romulan Neutral Zone.
In 2366, the location of Nelvana II was labeled on a Starfleet tactical intelligence analysis system map. This map illustrated the current position and orbital path of this planet. A tactical scan analysis of this planet by the USS Enterprise-D resulted in negative readings which Data interpreted as no unusual activity. The starship was scanning for artificially-generated power, reflected pattern return, subspace distortion, electromagnetic emissions, gravimetric perturbation, microwave enhancement, background radiation, particulate distribution, virtual interferometry, and low-level gamma imaging.
