Eerlik was a planet in the Alpha Quadrant of the Milky Way Galaxy, proximate to but separate from the United Federation of Planets. It was the homeworld of the Eerlikka people, and one of at least nine planets in its star system.
The planet was characterized by burgundy-colored oceans, and deep brown land masses. Eerlik was rich in uridium, which led to trade agreements with the Federation following first contact.
Eerlik had one moon, which was the base of Ganitriul, the artificial intelligence computer which controlled most of the technological aspects of Eerlikka society. (SCE eBook: Fatal Error)
