Pluto [SEP] Atmosphere
Pluto has a tenuous atmosphere consisting of nitrogen (N), methane (CH), and carbon monoxide (CO), which are in equilibrium with their ices on Pluto's surface. According to the measurements by "New Horizons", the surface pressure is about 1 Pa (10 μbar), roughly one million to 100,000 times less than Earth's atmospheric pressure. It was initially thought that, as Pluto moves away from the Sun, its atmosphere should gradually freeze onto the surface; studies of "New Horizons" data and ground-based occultations show that Pluto's atmospheric density increases, and that it likely remains gaseous throughout Pluto's orbit. "New Horizons" observations showed that atmospheric escape of nitrogen to be 10,000 times less than expected.
