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 .
Pluto has a tenuous atmosphere consisting of nitrogen (N 2), methane (CH 4), and carbon monoxide (CO), which are in equilibrium with their ices on Pluto's surface. [134] [135] According to the measurements by New Horizons, the surface pressure is about 1 Pa (10 μbar), [7] roughly
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.
10 kPa 1.5 psi Pressure increase per meter of a water column [26]: 10 kPa 1.5 psi Decrease in air pressure when going from Earth sea level to 1000 m elevation [citation needed]
During the post Pluto cruise, REX is normally turned on monthly to measure the electron density of the solar wind between Earth and the spacecraft. [8] When New Horizons flew by Pluto in 2015, it was at about 32.9 AU from the Sun, and about 43.6 AU for the New Year's Day 2019 flyby of Arrokoth. [9] [10]
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.
Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa ), which is equivalent to 1,013.25 millibars , [ 1 ] 760 mm Hg , 29.9212 inches Hg , or 14.696 psi .
