Why is Pluto covered with nitrogen, methane, and carbon monoxide ice?
Solar SystemPluto
Quick Answer
Pluto is extremely cold, so volatile gases freeze onto its surface as ices. Its thin atmosphere can also freeze out and return as the dwarf planet moves farther from the Sun.
The Full Story
Pluto is so cold, with surface temperatures around -230°C, that substances like nitrogen, methane, and carbon monoxide remain frozen as surface ices. These materials can cycle between the surface and Pluto’s thin atmosphere as the dwarf planet moves in its eccentric orbit. When Pluto is closer to the Sun, some of the ice sublimates into gas; when it is farther away, the gas refreezes. This makes Pluto’s surface one of the most chemically and seasonally active in the outer Solar System.
