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.
