    The only gases to have been identified in Pluto’s atmosphere so far are carbon monoxide and methane. Methane was identified first, with carbon monoxide only being identified as recently as 2011. The carbon monoxide on Pluto is extremely cold, at 364 degrees Fahrenheit. Methane has been found lower in the atmosphere of Pluto, which was only recently discovered to reach out a quarter of the distance towards Pluto’s largest moon – Charon. The atmosphere on Pluto is known to fluctuate in the lower regions. The atmospheric gases are though to be a result of the sun heating the icy surface of Pluto. This makes Pluto’s atmosphere the most fragile of our solar system. Scientist believe that top layers blow off into the cosmos.
