The climate of Pluto concerns the atmospheric dynamics, weather, and long-term trends on the dwarf planet Pluto. Five climate zones are assigned on the dwarf planet: tropics, arctic, tropical arctic, diurnal, and polar. [1] These climate zones are delineated based on astronomically defined boundaries or sub-solar latitudes, which are not ...
The presence of methane, a powerful greenhouse gas, in Pluto's atmosphere creates a temperature inversion, with the average temperature of its atmosphere tens of degrees warmer than its surface, [142] though observations by New Horizons have revealed Pluto's upper atmosphere to be far colder than expected (70 K, as opposed to about 100 K). [137]
The temperature on the surface is 40 to 60 K (−230 to −210 °C), [6] but it quickly rises with altitude due to a methane-generated greenhouse effect. Near the altitude of 30 km it reaches 110 K (−163 °C), where it then slowly decreases afterwards with height. [7] Pluto is the only trans-Neptunian object with a known atmosphere. [7]
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. [3]
Pluto needs 248 years for one complete orbit, and has been observed for less than one third of that time. It has an average distance of 39 AU from the Sun, hence in-depth data from Pluto is sparse and difficult to gather. Temperature is inferred indirectly for Pluto; when it passes in front of a star, observers note how fast the light drops off.

Geology of Pluto. The geology of Pluto consists of the characteristics of the surface, crust, and interior of Pluto. Because of Pluto's distance from Earth, in-depth study from Earth is difficult. Many details about Pluto remained unknown until 14 July 2015, when New Horizons flew through the Pluto system and began transmitting data back to ...
