Merak II, sometimes simply referred to as Merak, is a planet located in the space of the United Federation of Planets. Merak is the second planet of the Merak star system. Owing to the names of the stars in the system, this world can also be known as Beta Ursae Majoris II or Latis Cyrtiva II.
Merak was one of the first worlds that was colonized by the Vulcan race, Merak was a tropical world that was rich in radioactives and industrial crystals which were used to run power plants. The need for increased productivity resulted in the colonists removing much of the world's northern rainforests in order to make room for newer as well as more advanced facilities.
After the Four Years War, construction began on ship building facilities which produced vessels of various designs for Starfleet. In addition, it also served as an important commercial and trade center. (FASA RPG module: The Federation)
In the late 2260s, Merak experienced a bacterial infestation affecting botanical growth on the world. By 2269, the USS Enterprise had to obtain a supply of zenite ore that was used to create a preparation to use the toxic mineral to kill the plague. (TOS episode: "The Cloud Minders")
