There are five climate zones on Pluto which are defined by the sub-solar latitude, [1] each with specific boundaries. However, the latitude ranges of the climate zones expand and shrink in response to the obliquity range of Pluto from a minimum of 103° to a maximum of 127° over the 2.8 million year oscillation period.
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]
"Pluto is the first planetary body we know of where the atmospheric energy budget is dominated by solid-phase haze particles instead of by gases." Pluto is way cooler than it should be, and now we ...

This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group , derived from raw gridded climatologies from the Climatic Research Unit .
The average temperature in a local area must be zero degrees Celsius - or less - for seven days in a row, or be forecast to be below freezing for seven consecutive days. ... Pluto enters Aquarius ...
