No craters have been found, indicating that its surface must be less than 10 million years old. [16] A number of mechanisms are proposed to explain the absence of craters, including cryovolcanism (volcanoes erupting volatiles instead of magma), convective overturn, and viscous relaxation – processes that would erase negative topography.

Distribution of numerous impact craters and basins on both Pluto and Charon. The variation in density (with none found in Sputnik Planitia) indicates a long history of varying geological activity. Precisely for this reason, the confidence of numerous craters on Pluto remain uncertain. [117]
NASA's New Horizons team has just revealed the most detailed images of Pluto yet, and the space agency is ecstatic about what it has seen: a smooth, young, and active surface on what had been ...
According to New Scientist, the New Horizons principal investigator recently announced that ?liquids may have existed on the surface of Pluto in the past.? Pluto may have had liquid nitrogen ...
Dorothy is the largest known impact basin on Pluto's moon Charon. The crater was discovered by the New Horizons space probe in 2015 during its flyby of Pluto and its moons. It was named after Dorothy Gale from the novel The Wonderful Wizard of Oz. [1] The crater is located near Charon's north pole, and overlaps the edge of Mordor Macula.
NASA has released a map of Pluto's surface made from images recently taken by the New Horizons probe and it includes some quite mysterious features. ... could be the site of an impact crater or a ...
The geography of Pluto refers to the study and mapping of physical features across the dwarf planet Pluto. On 14 July 2015, the New Horizons spacecraft became the first spacecraft to fly by Pluto. [ 1 ] [ 2 ] During its brief flyby, New Horizons made detailed geographical measurements and observations of Pluto and its moons .
