When Pluto is closer to the sun in its orbit, the
warmth from the sun heats up the frozen ices of
nitrogen, methane and carbon monoxide on Pluto's
surface. These ices vaporize and form a temporary
atmosphere. When Pluto moves farther from the
sun, the atmosphere freezes and falls back onto
Pluto's surface. NASA Organization
