The overall change of atmospheric pressure in this model is about 4 times; the minimum was reached near 1970–1980, and the maximum will be near 2030. The full temperature range is only several degrees. [11] In July 2019, an occultation by Pluto showed that its atmospheric pressure, against expectations, had fallen by 20% since 2016. [45]
In July 2019, an occultation by Pluto showed that its atmospheric pressure, against expectations, had fallen by 20% since 2016. [140] In 2021, astronomers at the Southwest Research Institute confirmed the result using data from an occultation in 2018, which showed that light was appearing less gradually from behind Pluto's disc, indicating a ...
Lung air pressure difference moving the normal breaths of a person (only 0.3% of standard atmospheric pressure) [35] [36] 400–900 Pa 0.06–0.13 psi Atmospheric pressure on Mars, < 1% of atmospheric sea-level pressure on Earth [37] 610 Pa 0.089 psi Partial vapor pressure at the triple point of water (611.657 Pa) [38] [39] 10 3 Pa
Geology of Pluto. The geology of Pluto consists of the characteristics of the surface, crust, and interior of Pluto. Because of Pluto's distance from Earth, in-depth study from Earth is difficult. Many details about Pluto remained unknown until 14 July 2015, when New Horizons flew through the Pluto system and began transmitting data back to ...
The arctic climate of Pluto is defined as the latitude ranges that, during one orbit, experience both continuous sunlight during summer season and continuous darkness during winter season. The permanent arctic zones of the dwarf planet range from 90°N to 37°N in the northern hemisphere and from 90°S to 37°S in the southern hemisphere.
The geography of Pluto refers to the study and mapping of physical features across the dwarf planet Pluto. On 14 July 2015, the New Horizons spacecraft became the first spacecraft to fly by Pluto. [ 1 ] [ 2 ] During its brief flyby, New Horizons made detailed geographical measurements and observations of Pluto and its moons .
Hydrogen is considered a supercritical fluid when the temperature is above 33 K and the pressure is above 13 bar. [3] Since the lower boundary of the atmosphere is ill-defined, the pressure level of 10 bars, at an altitude of about 90 km below 1 bar with a temperature of around 340 K, is commonly treated as the base of the troposphere.

Angular diameter. 55 milli-arcsec [17] Charon (/ ˈkɛərɒn, - ən / KAIR-on, -ən or / ˈʃærən / SHARR-ən), [note 1] or (134340) Pluto I, is the largest of the five known natural satellites of the dwarf planet Pluto. It has a mean radius of 606 km (377 mi).
