Dera II is an uninhabited, L-class world orbiting a Class-F star. It is one of several planets that Starfleet installed sensor arrays on after the destruction of the Romulan homeworld. The arrays are tuned to detect the spread of radiation from the Hobus supernova, and are part of a 30-year study on the long-term effects of such an event on surrounding sectors.
