<P> The atmosphere of Pluto is the tenuous layer of gases surrounding Pluto . It consists mainly of nitrogen (N), with minor amounts of methane (CH) and carbon monoxide (CO), all of which are vaporized from their ices on Pluto's surface . It contains layered haze, probably consisting of heavier compounds which form from these gases due to high - energy radiation . The atmosphere of Pluto is notable for its strong and not completely clear seasonal changes caused by peculiarities of the orbital and axial rotation of Pluto . </P> <P> The surface pressure of the atmosphere of Pluto, measured by New Horizons in 2015, is about 1 Pa (10 μ bar), roughly 100,000 times less than Earth's atmospheric pressure . The temperature on the surface is 40 to 60 K (− 230 to − 210 ° C), but it quickly grows with altitude due to methane - generated greenhouse effect . Near the altitude 30 km it reaches 110 K (− 163 ° C), and then slowly decreases . </P>
