Matalas Prime was the main planet in the Matalas planetary system. This planet was visited by the Enterprise NX-01 during its historic mission of exploration in the mid-22nd century.
In 2152, while stranded on a moon with an increasingly rising temperature with an Arkonian named Zho'Kaan, Commander Charles Tucker III reminisced about some of the experiences he had while on Enterprise, including seeing the ringed moons of Matalas Prime. (ENT: "Dawn")
The name was an homage to Terry Matalas, onetime
Voyager production assistant and later the assistant to executive producer Brannon Braga.
