List of extraterrestrial dune fields
This is a list of dune fields not on Earth which have been given official names by the International Astronomical Union. Dune fields are named according to the IAU's rules of planetary nomenclature. The relevant descriptor term is undae. As of now, the only two Solar System planets, besides Earth, with named dune fields are Venus and Mars. Dune fields have also been discovered on Saturn's moon Titan, Pluto and comet 67P/Churyumov–Gerasimenko. Venus. There are three officially named dune fields on Venus. They are named after desert goddesses, as per the  IAU's rules. They are listed below. Mars. There are six officially named dune fields on Mars, which are named after nearby classical albedo features in accordance with the IAU's rules. Five of them lie between 75°N to 85°N, between Planum Boreum and Vastitas Borealis. These dune fields span over 200 degrees of longitude. The sixth, Ogygis Undae, lies on the southern hemisphere of Mars. They are listed below. Titan. There are five officially named dune fields on Titan, which are named after Greek gods, goddesses or personifications of wind. They are listed below: Literature  also uses names of dark albedo features when referring to Titan's dune fields: Pluto. Analysis of high resolution photos from New Horizons taken on 14 July 2015 of Pluto's Sputnik Planum region in 2018 has confirmed the presence of transverse dunes (perpendicular to the wind streaks) within the cellular nitrogen plains, spaced about 0.4 to 1 km apart, that are thought to be composed of 200-300 μm diameter particles of methane ice believed to be derived from the nearby Al-Idrisi Montes. These features are yet to be formally named. References. A large portion of this article  was sourced from the Gazetteer of Planetary Nomenclature, the official IAU database of planetary names.
