Delta Rana IV, also referred to as Rana IV, was the formerly inhabited fourth planet in the Delta Rana system. The planet had three moons. The planet was the home of a Federation colony in the 24th century. By 2366, the colony had a population of eleven thousand. A species of tea native to this planet was cultivated by the colonists and brewed for drinking. The colony lacked interstellar spacecraft. In that year, the Husnock destroyed both the colony and the planet, killing all save for one colonist. The planet surface was severely scarred. (TNG: "The Survivors" )
