The region experiences a continuous sunrise and sunset for each and every Pluto rotation period of 6.4 days over a time period of 10 million years. [1] The present-day diurnal climate zone of Pluto spans from 30°N to 30°S, encompassing 50% of the total surface area, due to the current axial tilt of 120°.
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]

At Pluto's ambient temperature of 38 K (−235.2 °C; −391.3 °F), nitrogen and carbon monoxide ices are denser and much less rigid than water ice, making glacial-like flows possible; nitrogen ice is the most volatile. [5] The nitrogen ice of the basin rests on Pluto's crust mostly composed of much more rigid water ice. [14]

Prepare for a time of renewal. Pluto, the planet of intensity, destruction, transformation and rebirth, will enter Aquarius on Nov. 19 and remain there until March 8, 2043.
This means that the surface temperature is reduced from the effective mean radiating temperature by 16%, which is a potentially significant cooling effect. [1] This is an ideal case and represents the maximum impact the anti-greenhouse effect can have and will not be the impact for a real planet or large moon.
