When Pluto is close to the Sun, its surface ices sublimate (changing directly from solid to gas) and rise to temporarily form a thin atmosphere. Pluto's low gravity (about 6% of Earth's) causes the atmosphere to be much more extended in altitude than our planet's atmosphere.

Pluto has a moderately eccentric and inclined orbit, ranging from 30 to 49 astronomical units (4.5 to 7.3 billion kilometres; 2.8 to 4.6 billion miles) from the Sun. Light from the Sun takes 5.5 hours to reach Pluto at its orbital distance of 39.5 AU (5.91 billion km; 3.67 billion mi).
Pluto is a dwarf planet located in a distant region of our solar system beyond Neptune known as the Kuiper Belt. Pluto was long considered our ninth planet, but the International Astronomical Union reclassified Pluto as a dwarf planet in 2006.
25 wrz 2019 · The surface of Pluto is composed mostly of about 98% nitrogen ice, with traces of methane and carbon monoxide. Nitrogen and carbon monoxide are most abundant on the anti-Charon face where Tombaugh Regio’s western lobe, Sputnik Planitia is located. It has mountains covered in water ice.
10 lis 2024 · An observer standing on Pluto’s surface would see the Sun as an extremely bright star in the dark sky, providing Pluto on average 1/1,600 of the amount of sunlight that reaches Earth. Pluto’s surface temperature therefore is so cold that common gases such as nitrogen and carbon monoxide exist there as ices.
Pluto's surface is remarkably varied, with large changes in both brightness and colour: The colour varies between charcoal black, dark orange and white. The surface of Pluto is thought to be composed of more than 98% nitrogen ice. As Pluto approaches the Sun, it is believed that these ices sublimate to form a thin atmosphere. Mantle
