Pluto's composition is unknown, but its density (about 2 gm/cm3) indicates that it is probably a mixture of 70% rock and 30% water ice much like Triton. The bright areas of the surface seem to be covered with ices of nitrogen with smaller amounts of (solid) methane, ethane and carbon monoxide.

The composition of the darker areas of Pluto's surface is unknown but may be due to primordial organic material or photochemical reactions driven by cosmic rays. Little is known about Pluto's atmosphere, but it probably consists primarily of nitrogen with some carbon monoxide and methane.

The pictures will be useful to help us understand other observations which in turn tell us about Pluto's formation. For example, one important clue to the formation is knowing the bulk composition of Pluto. We know the surface is covered with N2, CH4, and CO but this only tells us what's on the top of the surface.

The absence of carbon dioxide absorptions is one of several differences between the spectra of Pluto and Triton in this region. Both worlds carry information about the composition of the solar nebula and the processes by which icy planetesimals formed.
