Njura is a planet located in the galaxy's Alpha or Beta Quadrant. It is the largest inhabited planet in its star system and the homeworld of the advanced Njuran civilization.
Njura features two very large islands and four continents, three of which contact its equator. Although Njurans did not develop a weather modification network, the planet's weather was tracked and predicted accurately by a central meteorological center. Eleven massive nuclear reactors transmitted energy via orbital satellites to supply public electricity. Two such generators could supply power to 100 million people.
By the 13th century, Njurans had developed spacecraft and begun to colonize neighboring planets. For the next millennium, Njura was the center of an interplanetary empire.
In the 23rd century, a generation-long civil war led to democracy on Njura and independence for its four colony worlds in 2260.
In 2270, Njura celebrated the tenth anniversary of disarmament. A landing party from the USS Enterprise attended a parade and stadium gala. (TOS comic: "To Err Is Vulcan")
