Dune, formally known as Arrakis, is a desertplanet featured in the Dune series.
In Dune, the planet is the home of the Fremen and the only source of "Spice" in the universe. Arrakis is the third planet orbiting the star Canopus, and it in turn is orbited by two moons, one of which has the image of the desert kangaroo mouse, "Muad'Dib", on it; the other moon possesses the image of a human hand.
On April 5, 2010, a real-world plain of Saturn's moon Titan was named "Arrakis Planitia" after Herbert's fictional planet.
