Arrakis
Arrakis—informally known as Dune and later called Rakis—is a fictional desert planet featured in the Dune series of novels by Frank Herbert. Herbert's first novel in the series, 1965's Dune, is popularly considered one of the greatest science fiction novels of all time, and it is sometimes cited as the best-selling science fiction novel in history. In Dune, the planet is the home of the Fremen, and subsequently is the Imperial Capital of the Atreides Empire. Arrakis is the third planet orbiting the star Canopus, and it in turn is orbited by two moons, one of which has an albedo pattern resembling the desert kangaroo mouse, Muad'Dib, on it; the other moon has markings resembling a human hand.
