Donico II was a class M planet, the second planet of the Donico system, located not far from Starbase 19 in or near Federation space in the mid-23rd century, and homeworld of the Donican people.
History and specifics[]
Surface features included cities, monorails, and willow-like trees.
In the year 2209, the planet suffered a notable drought. The world's revisionist government erased that fact from their communications network and computer records, instead claiming that the world always had healthy rains.
The Starfleet starship USS Enterprise visited Donico II in 2267 after receiving a distress call warning of the imminent collapse of "the Grid", Donico II's planetary power distribution system. Although the political leadership denied any problem upon the ship's arrival, Lieutenant Commander Montgomery Scott and Lieutenant Nyota Uhura persisted in their efforts to alleviate the situation.
