The USS Copernicus (NCC-640) was a Federation Oberth-class scout in service to Starfleet in the late 23rd century.
In the year 2286, soon after the Whale Probe departed Earth's orbit, the Copernicus returned to Earth and was docked within Earth Spacedock. (TOS movie: The Voyage Home)
In 2291, around stardate 8812.1, the Copernicus was ordered to rendezvous with the Constitution-class starships USS Endeavour and USS Enterprise at Starbase 40. (TOS comic: "Split Infinities")
- The Copernicus was named for Nicolaus Copernicus, who developed the heliocentric theory of the solar system.
- The Star Trek Encyclopedia lists the Copernicus' registry number as NCC-623, although it can be seen as NCC-640 on screen in Star Trek IV: The Voyage Home.
