Nelvana V was the uninhabited first planet of the Nelvana system. The planet was located within the Federation-Romulan border in the Beta Quadrant.
In 2366, Nelvana V's location 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.
