. Dune fields are named according to the IAU's rules of planetary nomenclature

Planetary nomenclature

Planetary nomenclature, like terrestrial nomenclature, is a system of uniquely identifying features on the surface of a planet or natural satellite so that the features can be easily located, described, and discussed. The task of assigning official names to features is taken up by the International...

. The relevant descriptor term is undae. As of now, the only two solar system bodies besides Earth with named dune fields are Venus

Venus

Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. The planet is named after Venus, the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of −4.6, bright enough to cast shadows...

Mars

There are five officially named dune fields on Mars, which are named after nearby classical albedo features

Classical albedo features on Mars

The classical albedo features of Mars are the light and dark features that can be seen on the planet Mars through an Earth-based telescope. Before the age of space probes, several astronomers created maps of Mars on which they gave names to the features they could see. The most popular system of...

Planum Boreum

Planum Boreum is the northern polar plain on Mars. It extends northward from roughly 80°N and is centered at . Surrounding the high polar plain is a flat and featureless lowland plain called Vastitas Borealis which extends for approximately 1500 kilometres southwards, dominating the northern...

 and Vastitas Borealis

Vastitas Borealis

Vastitas Borealis is the largest lowland region of Mars. It is in the northerly latitudes of the planet and encircles the northern polar region. Vastitas Borealis is often simply referred to as the Northern plains or Northern lowlands of Mars. The plains lie 4–5 km below the mean radius of...

• Abalos Undae
• Hyperboreae Undae
• Olympia Undae
  Olympia Undae
  Olympia Undae is a vast dune field in the north polar region of the planet Mars. It consists of a broad “sand sea” or erg that partly rings the north polar plateau from about 120° to 240°E longitude and 78° to 83°N latitude. Stretching about across and covering an area of 470,000 km2,...
