Namib Sand Sea
Planetary aeolian dunes are a common feature within the solar system, and recent work has identified the potential presence of dunes on the dwarf planet, Pluto. The presence of these dunes is made possible because of Pluto’s thin, tenuous atmosphere. The researchers, led by Matt Telfer, found that these methane ice dunes within the Sputnik Planitia region are regularly spaced and have linear ridges. They suggest that these are transverse dunes that have a wavelength between 0.4 to 1 km. These relatively undistributed dunes could potentially be geologically young.
