The surface pressure of the atmosphere of Pluto, measured by New Horizons in 2015, is about 1 Pa (10 μbar), roughly 1/100,000 of Earth's atmospheric pressure. 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 .
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).

Moores and his colleagues hypothesize that Pluto's penitentes grow only during periods of high atmospheric pressure, at a rate of approximately 1 centimeter per orbital cycle. These penitentes appear to have formed in the last few tens-of-millions of years, an idea supported by the sparsity of craters in the region, making Tartarus Dorsa one of ...

[7] [8] Long-term climate cycles of planetary bodies (e.g., Earth) are associated with axial precession and variations in the obliquity [9] and orbital eccentricity. [10] However, in the case of Pluto, the orbital eccentricity and axial precession cycles have less influence on the climate cycles of the dwarf planet than the obliquity variation.
The distance between Charon and Pluto is about 12,200 miles (19,640 km), compared to the 238,855 miles (384,400 km) on average separating Earth from its moon.
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.. According to PEOPLE's ...
