Terra Nova system

The Terra Nova system is a star system located around 20 light years from the Sol system, in the Alpha Quadrant.

In 2087, the Terra Nova colony was established on the third planet of the system by Humans, attempting to prove that Humans could actually establish a colony in deep space. In 2161, the system became a member of the United Federation of Planets. (ENT episode: "Terra Nova" and Star Trek: Star Charts).

During 2277, in the mirror universe, Grand Admiral Matthew Decker assembled a task force in the system in the hopes of ambushing the ISS Enterprise and killing Admiral Spock. However, mutinies aboard the starships loyal to Decker, meant that Spock was able to seize control of the fleet and declare himself the Grand Admiral of the Imperial Starfleet in Decker's place. (TOS novel: Glass Empires: The Sorrows of Empire).
