Does Pluto have an atmosphere?
Question Date: 2013-12-10
Answer 1:

Yes, Pluto has an atmosphere, it is mainly made of the gas methane. The atmosphere in Pluto sometimes collapses and the methane gas condenses to ice! This happens when Pluto is farthest from the Sun, which we call Aphelion. When Pluto is closest to the Sun (Perihelion), its atmosphere is present. We say that Pluto has a TRANSIENT atmosphere, depending on where Pluto is located on its orbit around the Sun.
